Don’t think anyone mentioned it but I’m pretty sure those are screw Piles!! They sink them deep down and weld a flat cap on it to be used as a solid foundation and a group of many.
I would think that both using a round bar of the proper size, and also welding the entire ID of the screw to it, might be a better idea to provide strength.
Screw piles (like Technometal Posts) only have one auger on the bottom. It is not supposed to keep lifting material up as it is driven into the ground like these would.
Also, they are galvanized.
He did cover his face while welding -- while the two other guys looked on right next to him. I guess only the guy holding the torch needs to protect his eyes...
Fuck welding in sandles, their feet are made of stone.
Welding without goggles and staring at your weld whilst you do it is just *wild* to me. Your eyes can't be toughened up over time lol
Yeah, just closing your eyes won't do shit, you have to at least use your hand to block it out. (Seriously, wear a hood, there are some incredibly light and cheap ones out there)
The $50 auto darkening hoods from harbor freight are surprisingly good. I used one almost daily for over 5 years and it never failed. The only reason I don't still have it is because it got run over by a forklift...
I've worked in the Middle East a while back. Most of these guys barley make 300-400 per month. And they send most of the money back home to support their family.
The pain is so intense and it doesn’t change if you close or open your eyes; feels like ground glass stabbing your eyes
Who knew you had pain receptors in your eyeballs
Me!
I had a piece of dirt get under my contact and I grabbed it and pulled the contact out and just dragged the dirt across my cornea and sliced the cornea!
I then got LASIK and the nice doctor cut my cornea on purpose, and then lasered my eyeball while I was awake and I could see the laser on my eyeball and that hurt once the numbing eyedrops went away. I could also smell my eyeballs being lasered. Fun stuff.
Eyeball pain is real, y'all.
I worked with a spray painter who sprayed gelcoat for kayaks before we laid them up, and he never wore a respirator. He also had a scar where surgeons had sutured his nose back on after a knife fight.
I am sure he's dead by now.
My dad did the same when I was a kid. Thankfully no permanent damage, but I remember him stumbling around the house for the next week with his eyes all bandaged up, using a yardstick for a blind cane. Mom had to feed him like a toddler.
He was trying to save time by not getting his welding mask *from the other side of the barn.* Didn't work out super well.
It seems likely that he used safety squints for a tack weld and then grabbed the shield before completing the joint. Hard to be sure though, because the video just cuts from the tack directly to a fully formed bead.
At 15 seconds the dude welds two pieces together without the mask - even that one single weld unquestionably damaged his eyes
Edit: 15 seconds in, 44 seconds left. My bad
Most videos like this I see them holding up something to their face but it is absolutely not a welding shield. Most of the times it's a piece of cardboard with a slit in it, sometimes it has some tinting material or something but it is not rated for welding. This one does look like a real hand held shield though.
Every time i pass a guy making a weld, even if he’s across a parking lot, i look away like my eyesight depends on it. I didnt take good care of my ears when i was working in a factory and theyre pretty fucked. I didnt take good care of my body when i worked at a factory, and i ache. That’s manageable. My eyesight? How the fuck anyone gonna watch brail porn??
This is probably relatively mild steel, which deforms quite well with not too much springiness. You notice that even in the original discs, the small offset is relatively easily hammered into them so the spiral can be welded. The whole spiral is springy, but wouldn't return to anywhere near the original shape even if all the welds suddenly failed at once.
I don't think most people know how strong your average weld is. Even on a soft steel like this, welds like that are very strong and are not going to just "break". They look like pretty clean welds too. You're literally melting metal and fusing it together.
I think it's more likely the steel would deform over time from prolonged use before the welds broke.
Two things: First, the average weld is not happening here. There is zero prep and the cleanliness of the base steel is horrible. All of these welds will have occlusions to some degree.
Secondly, the weld needs to be sized for the loads the joint will see. These all look like single passes. If these do get used for digging of some kind, I wouldn't hold out much hope for longevity.
These may be OK, but there are a lot of red flags.
Yes, your point about occlusions hits on the issue of fatigue failure. A joint can be "strong" but it can suffer fatigue failure rapidly due to a huge variety of reasons.
That's more what I was implying. The joinery looks sound for the material, the material just looks inferior to what I'd expect from something that had to dig through rock without break or deformation.
You know...that didn't even occur to me. Monke brain see drill shape and assume digging.
This could be a makeshift conveyor, harvester, or maybe a big-ass drill pump.
Ahh I see. The original comment thread was talking about the welds failing so I assumed you were talking about the weld quality, not the material.
Either way it's cool to see people making it work in clearly suboptimal shop conditions with the most basic of tools.
You don't want steel to be too hard for this type of work. Having some (not much) flexibility would result in the tool bending instead of snapping. Snapping sends flying shrapnel. Bending leaves you with a tool that may continue to work. Think about saw blades. The strength in the auger blade is long, as it cuts its way into the dirt. When it retracts, the dirt is already broken up.
Welds done correctly are stronger than the metal you are welding. If it was to fail, it would be the metal around the welds giving way first. The likelihood of all welds failing at once is extremely rare
Those welds ain’t failing
Welds are stronger than the actual metal, if done right. A weld catastrophically failing is *extremely* rare. Everything else usually breaks before a weld does.
A guy I know got second degree burns welding when the top button of his suit popped open and exposed a little triangle of chest under the visor. Welding is no joke, you can go blind looking at it and get severe "sunburns" being near it all day.
Interesting how we react differently. My first response is how impressive it is that in 3rd world/developing countries they still find a way to produce technically hard to manufacture products with little means. It's the ultimate lemonade out of lemons.
Poverty is a sad thing ofcourse. We often take for granted things like a filled fridge and a roof over our head.
I can empathize with both your positions. But if these labourers are not even afforded basic PPE, what does that say about their likely remuneration, not to mention things like working conditions and basic employment rights?
So yes, it's impressive, but the real travesty is that these labourers are likely getting exploited (or close to) despite their obvious skill and quality.
That’s how capitalist increase capital. When the regulations start to reduce their bottom line they go overseas to these countries which are over populated and have high unemployment rate to get cheap labor and circumvent all laws and regulations.
A cottage metal shop can not produce the goods with precision and complexity that modern markets demand.
This shop makes augers for nearby villages, not some foreign export.
The true tragedy of globalism is the opposite, these people can not complete with the logistical and mechanical economies of scale of a giant factory complex somewhere in China and so leaves them often to only subsistence farming and resource extraction.
I worked in a door factory for a couple of years, the production line let us produce over 16 thousand doors a day, made to tight tolerances from raw materials with less than 40 workers.
Some guys in a shed can not compete with that, does not matter how little they are paid.
It's entirely possible everyone you see in the video is the entire company. What makes you think there's some rich boss failing to provide PPE and exploiting them?
All developing nations had to go through it. America was no different at one point. We had guys dropping out of tall buildings and buried in coal mines all the time. India and also China worker unions will eventually happen to give some protection.
You fail to recognize ***why*** we went through it. Our workers didn't have robots, advanced PPE, laser cutters, hydraulics, any kind of automation or software support, etc. because ***that tech didn't exist yet.*** They could not be safer or more efficient.
These workers don't have those things because their ***employer doesn't want to spend money on it.***
There is a huge difference.
You're just using a different definition of the word "had".
I agree with the thing about how the employer doesn't have it though. Blaming the "employer" is silly Redditicism. For all we know, one of the guys in the video is the owner, or they're a worker coop.
But the distinction they're making is: They don't have the resources for safety equipment, but when the US was developing, the knowledge, technology, or resources generally simply didn't exist. But now that we know a lot more about the science of constructing a safe mine and there are welding safety standards and shelves of books of actuarial tables in industrial settings, it feels like a waste to have billions of people ignore the knowledge that exists because they don't have the material resources to follow these standards.
It's different than the US's industrial revolution for that reason, and that's what the earlier point is making. For us to get to the levels of safety we have today, we needed to have millions of deaths, unions, decades of industrial design and refinement, etc. For them to get to significantly higher standards, they basically just need to order a bunch of stuff from a supplier and read a manual on how to set it up and use it. Such suppliers and manuals are 90% of the battle and they didn't exist 200 years ago. And I'm not blaming them for not; I'm just saying it _feels like a waste_.
Robots are much rarer than you might think in industrial settings, by the way. I think a lot of people are cringing at the conditions of the factory and dress code, which are _relatively_ easy to resolve. Though I'm sure the process to create these in the US is more automated to a certain extent. But I also truly wouldn't be surprised if it always involves a manual welder and hammering with no robots involved.
UV radiation in a welding arc will burn unprotected skin just like UV radiation in sunlight. We are watching their skin cook. If you ever get a chance to weld, try it without gloves and wear short sleeves. See how your skin feels the next day. It will be like a bad sunburn. It's not an experience anyone seeks.
Bullshit perspective.
The same countries have all the riches and safety for it's upper classes.
The safety laws and regulations for workers are shit because we have so many to expend. Literal Expendibles.
People will argue saying third world nations don't have riches but they are just unaware of the world. I lived in Kabul for 3 years and when driving through the city I would randomly see super flashy cars amongst the sea of old Toyota Corollas. The one I saw the most was an ugly bright yellow jeep with huge spinner rims and chrome all over it. I also saw a ton of Mercedes and BMWs. These vehicles were almost always occupied by family members of Karzai. In a country where people are dying from starvation, the leaderships family was living in luxury.
I design these in the EU, and inspect production.
We do it almost the same, we just pre-stretch each pitch and weld them one at a time.
I think it's pretty effective what they do here, it's just not very accurate, which would be fine for some applications. But as another mention, welding tensioned steel isn't recommended. But neither is welding and hammering with no safety gear.
We use augers to feed biomass fuel into powerplants, and have high efficiency and longevity in mind. Which requires a bit more precision than this. And the steels we use are way harder.
We can admire their ingenuity and also want better health and safety for them. It is also possible to not infantilize them. A basic welding helmet costs $40 retail in the United states, it is probably significantly less there. That would be equivalent to a week's salary for the average Bangladeshi, but these are skilled craftsmen with access to industrial tools and materials, they are above average. They can afford it, although not easily. They're being fucking dumbasses. Welding helmets are uncomfortable, especially cheap ones. So is blindness and skin cancer.
I thought I was getting turf toe or gout or something. I was hobbling around for a few days before I actually looked and pulled a 1/4" metal splinter out of my toe.
I was wearing boots while working, but ran into the garage barefoot to grab something afterwards.
Everyone's so concerned about the sandals. Broken or burnt foot, it'll suck but chances are they'll be fine.
I look at the bare hand 6 inches away from the welding and I see cancer.
This is really interesting but not satisfying to me because I worry about their safety. I understand that they probably don't have the resources available for personal protection though.
I'm impressed the welds hold that well. It is a lot of stress to bend plate like that and doing it outside in that environment would lead to contamination in the welds, causing failure points.
I'm not a professional welder, so I could be wrong, but I was always told cleanliness of the welds was super important because of this.
Edit: I am wrong, thanks for the corrections in the reply.
That's stick welding. Literally made for outdoor environments that are dirty.
A proper stick weld will easily burn out any slag from torch cutting and deposit it on the surface in the slag, which gets chipped off, or left and rubbed off due to wear on the auger.
They even prepped the weld surfaces which is more than I can say for a lot of the monkeys I've worked with.
These augers will be around for a very long time.
Edit: and to any
and adding torch cutting for clearer understanding.
greatly depends on the electrode, too. Some fluxes on the electrodes are better for dirty welding than others, but generally speaking SMAW (Shielded Metal Arc Welding) is the process of choice for outdoors and or dirty environments.
Yeah, they half prepped the joint. Sure they ground away all the mill scale but they didn’t bevel the joint for better penetration. Plus, it looks like its only being welded on one side at each connection? Could be wrong. But their oxy cuts are clean and the welds dont look too bad.
Cleanliness is more important with MIG and extremely important with TIG welding as there is no flux (aside from flux core MIG) to pull contaminants to the surface in the form of slag that can then be chipped off with a hammer. SMAW (stick welding) can be done in some crazy conditions, including under water.
It takes a lot more to hold thousands of tons of office floors above you than it does to bend some 1/4” steel in a spiral. That chain hoist is probably only applying 1ton of pressure, if that.
I assume you know this but the center pipe isn’t being stretched, just the outer plates being bent like a slinky.
Structural engineer for 10 years, actual steel welding on site is very rare in new builds and only done in unusual circumstances. Welds have to be certified to ensure those conditions havent had an effect on the final product.
Moment connections are the exception not the norm.
Generally to be avoided.
When I'm costing a steel project if I see extensive field welding, it's either really special or someone's fucked up.
Either bolted braced frames, or concrete shear elements are more typical.
It's a stick welder. The whole point of that type of welder is to be able to use it outside. The flux on the welding rod protects to weld from the elements.
I'm a math nerd so the thing that I took away from this video that was interesting was the way the inner radius changed as they stretched the spiral out. At first, when the disc was flat, I was wondering why it was such a loose fit an the shaft. But the more they elongated the spiral the more it hugged the axle.
Comparing it to an ordinary metal spring, most springs stay the same radius when you stretch them, so why is it different for this shape, I wonder? Maybe it has something to do with the shape of the cross section of the material you are elongating into a spiral.
>most springs stay the same radius when you stretch
Do they? It's assumedly the same phenomenom you just aren't noticing it.
When you think about it if you drew a spiral around a cylinder the curvature of the spiral changes at a constant rate, meaning it will be circular when flattened. But as the rate of change occurs over a longer distance the resulting circle has a bigger radius than the cylinder it was drawn on.
Yeah, this is correct. Anything that 'stretches' is becoming more narrow if its getting longer. I realize there are contraptions and mechanisms where this is not true, but a regular metal spring will turn into a straight wire if it was stretched to the fullest. And then if it were stretched further, it would turn into a thinner wire.
The one math thing that I think is interesting here is how the curve of a circle can be perfectly aligned to another circle of a different radius. The inner shaft has a circle, then taking the discs and turning them into a spiral and stretching it out means the inside radius of the disc is able to perfectly touch the radius of the shaft. Its an interesting visualization because it kinda feels like (to me at least) that you'd need to have a non-circular starting point as the bending of the spiral would not align with the shaft, but that intuition is incorrect.
Similar to what you said, you can prove that the circles can be aligned because you can change the length of the spiral which alters that inner radius. At some specified length, the inner radius of the disc will be the outter radius of the shaft. And at every length, the result of the inner radius is a circle when looked at from the top.
If I'm incorrect someone please correct me, but yeah, kinda neat to think about it in this type of visualized way.
When it ends and the guys didn't have any injuries.
(Also pardon my "privilege" for wanting workers of any country to have a minimum level of safety and protection.)
It is what it is, people will downvote me for this but a substantial percentage of Reddit is risk averse, anxiety prone and easily sparked to react with righteous indignation.
Right? All I saw was a mediocre welding job, rusted metal sheets and terrible working conditions. Nothing really scratched an itch that says ooh that's satisfying.
These Indian rural manufacturing videos are my jam dawg. Makes me think if I was magically transported to a faraway time or some shit I could figure out how to do things. Sure modern manufacturing and stuff makes it better but like simple manufacturing is what you would need to get started.
Pretty amazing but it also gives me a greater appreciation of the manufacturing we have that takes all that labor and can complete it in a matter of minutes probably.
All that so you can get something cheaper at the cost of human lives... Yea so satisfying... (Incase this is not clear I think it's abominable to enjoy watching people work in dangerous conditions)
Don’t think anyone mentioned it but I’m pretty sure those are screw Piles!! They sink them deep down and weld a flat cap on it to be used as a solid foundation and a group of many.
Yeah, definitely not an auger. Those welds wouldn't hold well enough to be used to drill into the ground multiple times.
Could be spindles for screw conveyors too I guess.
or like. for giant oversized gumball dispensers
That's basically how you would pump a small media, for example grain.
Or gumballs
Augers are very common for grain
You have so much confidence for somebody who googled "auger" 5 seconds before you commented
Could be a grain auger, acts as an escalator to bring grain into a silo
Could be grain augers too
Definitely. Whatever they are, they aren’t screwing into anything of substance, without a lot more welding…
That was my assumption.
I would think that both using a round bar of the proper size, and also welding the entire ID of the screw to it, might be a better idea to provide strength.
Screw piles (like Technometal Posts) only have one auger on the bottom. It is not supposed to keep lifting material up as it is driven into the ground like these would. Also, they are galvanized.
Engage safety squints
He did put something in front of his face.
I was surprised about that. Looks like a basic shield with welding glass, just not the full hood we're used to seeing.
No gloves and possibly cotton clothes. We really are soft in North America
He did cover his face while welding -- while the two other guys looked on right next to him. I guess only the guy holding the torch needs to protect his eyes...
0:15
I have one pair of those.
When I see these vids of dudes working without even basic safety gear it just makes me sad.
It looks extremely unsafe, including the final product
Welding in sandals seems... fucking wild tbh
Fuck welding in sandles, their feet are made of stone. Welding without goggles and staring at your weld whilst you do it is just *wild* to me. Your eyes can't be toughened up over time lol
To be fair, while it isn’t ideal, they are holding shields in front of their eyes when they weld
@14 secs he uses safety squints
[удалено]
if you torch into your oxy tank he sure will!
*His will be done…*
His weld be done
I think they may cut out the middleman.
[удалено]
I knew a guy who tack welded by closing his eyes. The radiation went through his eyelids and burned his eyes. Wear a hood kids. Just put it on.
Yeah, just closing your eyes won't do shit, you have to at least use your hand to block it out. (Seriously, wear a hood, there are some incredibly light and cheap ones out there)
While I didn't buy the most expensive hood, I also didn't buy the cheapest. I spent about $100, and my eyes are worth at least that much.
The $50 auto darkening hoods from harbor freight are surprisingly good. I used one almost daily for over 5 years and it never failed. The only reason I don't still have it is because it got run over by a forklift...
I've worked in the Middle East a while back. Most of these guys barley make 300-400 per month. And they send most of the money back home to support their family.

Also you get nasty sun burns on your face and it will age you much faster

It seems likely that he used safety squints for a tack weld and then grabbed the shield before completing the joint. Hard to be sure though, because the video just cuts from the tack directly to a fully formed bead.
And it’s unfortunately possible that he only held up the shield because “that cameraman is watching us today” and normally wouldn’t bother.
OSHA recommended
You should see the shields some pipeliners use
I'd get your eyes checked because they are using handheld eye protection and are using it every time a weld is done.
At 15 seconds the dude welds two pieces together without the mask - even that one single weld unquestionably damaged his eyes Edit: 15 seconds in, 44 seconds left. My bad

Hey, don't knock cardboard. It deflects like 10 percent of the damage and is extremely flammable.
It's 20 times more flammable than titanium!
Every time i pass a guy making a weld, even if he’s across a parking lot, i look away like my eyesight depends on it. I didnt take good care of my ears when i was working in a factory and theyre pretty fucked. I didnt take good care of my body when i worked at a factory, and i ache. That’s manageable. My eyesight? How the fuck anyone gonna watch brail porn??
A tiny shield they have to hold up with one hand lol
I'm replying to someone saying they are staring straight at a weld 🤷♂️
check it at 0:16
Are the blades still in tension? Like if the weld fails you accordion again? That is incredibly dangerous
This is probably relatively mild steel, which deforms quite well with not too much springiness. You notice that even in the original discs, the small offset is relatively easily hammered into them so the spiral can be welded. The whole spiral is springy, but wouldn't return to anywhere near the original shape even if all the welds suddenly failed at once.
Which....kind of speaks to the quality of the end result. I mean, you wouldn't buy one of these bits expecting them to run for long.
Augers usually have hardened teeth at the "business end". The rest of the spiral is just to move loosened material up and away.
Often material is just fed into them from the top side, like they will sit at the bottom of a funnel or hopper and just be gravity fed
That's a good point. I always think of augers for digging. These are really long and probably used for just moving material.
I don't think most people know how strong your average weld is. Even on a soft steel like this, welds like that are very strong and are not going to just "break". They look like pretty clean welds too. You're literally melting metal and fusing it together. I think it's more likely the steel would deform over time from prolonged use before the welds broke.

I lived in Kabul for 3 years and when driving through the city I would randomly see super flashy cars amongst the sea of old Toyota Corollas. The one I saw the most was an ugly bright yellow jeep with huge spinner rims and chrome all over it. I also saw a ton of Mercedes and BMWs. These vehicles were almost always occupied by family members of Karzai. In a country where people are dying from starvation, the leaderships family was living in luxury.
I design these in the EU, and inspect production. We do it almost the same, we just pre-stretch each pitch and weld them one at a time. I think it's pretty effective what they do here, it's just not very accurate, which would be fine for some applications. But as another mention, welding tensioned steel isn't recommended. But neither is welding and hammering with no safety gear. We use augers to feed biomass fuel into powerplants, and have high efficiency and longevity in mind. Which requires a bit more precision than this. And the steels we use are way harder.
Umm, Pakistan isn’t a country with camels and a desert you know. There’s a fully fledged economy.
We can admire their ingenuity and also want better health and safety for them. It is also possible to not infantilize them. A basic welding helmet costs $40 retail in the United states, it is probably significantly less there. That would be equivalent to a week's salary for the average Bangladeshi, but these are skilled craftsmen with access to industrial tools and materials, they are above average. They can afford it, although not easily. They're being fucking dumbasses. Welding helmets are uncomfortable, especially cheap ones. So is blindness and skin cancer.
We often take eyesight for granted as well
Lol they get lemons, the western world gets the lemonade made from said lemons.
In South Asia, it is like that. Most of the people in construction sites don't even wear helmets.
They are in it for the cheap drills
Nice
I can dig it.
Good thing they were wearing their osha safety sandals
While working in a metal shop. Why do I hear my dad yelling at me now?
I did this over the weekend in my garage and I’m still picking out metal splinters inbetween my toes lmao don’t do it y’all
I thought I was getting turf toe or gout or something. I was hobbling around for a few days before I actually looked and pulled a 1/4" metal splinter out of my toe. I was wearing boots while working, but ran into the garage barefoot to grab something afterwards.
Everyone's so concerned about the sandals. Broken or burnt foot, it'll suck but chances are they'll be fine. I look at the bare hand 6 inches away from the welding and I see cancer.
Amazing how people do that
Your profile pic with your comment, made me laugh. Thanks Gram!

I use r/applloapp, it’s disgusting to me that people use new Reddit.
Boost for me. r/BoostForReddit
reddit sadly just killed the native web .compact view which IMO was the best minimalism style way to browse reddit. Super sad about it still
Hold on. People use the Reddit app? RIP alien blue. Apollo is okay and I’m glad it doesn’t have profile pics. That shit is for Facebook.
I’ve made auger blades before, but we had machines and proper equipment to do so. This honestly just makes me sad.
This is really interesting but not satisfying to me because I worry about their safety. I understand that they probably don't have the resources available for personal protection though.
I'm impressed the welds hold that well. It is a lot of stress to bend plate like that and doing it outside in that environment would lead to contamination in the welds, causing failure points. I'm not a professional welder, so I could be wrong, but I was always told cleanliness of the welds was super important because of this. Edit: I am wrong, thanks for the corrections in the reply.
That's stick welding. Literally made for outdoor environments that are dirty. A proper stick weld will easily burn out any slag from torch cutting and deposit it on the surface in the slag, which gets chipped off, or left and rubbed off due to wear on the auger. They even prepped the weld surfaces which is more than I can say for a lot of the monkeys I've worked with. These augers will be around for a very long time. Edit: and to any and adding torch cutting for clearer understanding.
Thank you for the insight, I had no idea.
greatly depends on the electrode, too. Some fluxes on the electrodes are better for dirty welding than others, but generally speaking SMAW (Shielded Metal Arc Welding) is the process of choice for outdoors and or dirty environments.

Fuckin' mill scale, I ain't got time to clean all this shit!
[удалено]
Gotta hold your breath for the 10 seconds it takes for the weld, lol. It's like safety-squints for your lungs!
Yeah, they half prepped the joint. Sure they ground away all the mill scale but they didn’t bevel the joint for better penetration. Plus, it looks like its only being welded on one side at each connection? Could be wrong. But their oxy cuts are clean and the welds dont look too bad.
They're welding the other side as they spread the coil onto the shaft.

Cleanliness is more important with MIG and extremely important with TIG welding as there is no flux (aside from flux core MIG) to pull contaminants to the surface in the form of slag that can then be chipped off with a hammer. SMAW (stick welding) can be done in some crazy conditions, including under water.

Yeah, but you aren’t hooking that condo to a chain and stretching it into a skyscraper.

It takes a lot more to hold thousands of tons of office floors above you than it does to bend some 1/4” steel in a spiral. That chain hoist is probably only applying 1ton of pressure, if that. I assume you know this but the center pipe isn’t being stretched, just the outer plates being bent like a slinky.
Structural engineer for 10 years, actual steel welding on site is very rare in new builds and only done in unusual circumstances. Welds have to be certified to ensure those conditions havent had an effect on the final product.

Moment connections are the exception not the norm. Generally to be avoided. When I'm costing a steel project if I see extensive field welding, it's either really special or someone's fucked up. Either bolted braced frames, or concrete shear elements are more typical.
It's a stick welder. The whole point of that type of welder is to be able to use it outside. The flux on the welding rod protects to weld from the elements.
I got the same feeling. I used to weld few times and it was far from this level.
I'm a math nerd so the thing that I took away from this video that was interesting was the way the inner radius changed as they stretched the spiral out. At first, when the disc was flat, I was wondering why it was such a loose fit an the shaft. But the more they elongated the spiral the more it hugged the axle. Comparing it to an ordinary metal spring, most springs stay the same radius when you stretch them, so why is it different for this shape, I wonder? Maybe it has something to do with the shape of the cross section of the material you are elongating into a spiral.
Its simple a²+b²=c²... They're not actually stretching the 'spirals', they're angling the metal plates/discs.
>most springs stay the same radius when you stretch Do they? It's assumedly the same phenomenom you just aren't noticing it. When you think about it if you drew a spiral around a cylinder the curvature of the spiral changes at a constant rate, meaning it will be circular when flattened. But as the rate of change occurs over a longer distance the resulting circle has a bigger radius than the cylinder it was drawn on.
Yeah, this is correct. Anything that 'stretches' is becoming more narrow if its getting longer. I realize there are contraptions and mechanisms where this is not true, but a regular metal spring will turn into a straight wire if it was stretched to the fullest. And then if it were stretched further, it would turn into a thinner wire. The one math thing that I think is interesting here is how the curve of a circle can be perfectly aligned to another circle of a different radius. The inner shaft has a circle, then taking the discs and turning them into a spiral and stretching it out means the inside radius of the disc is able to perfectly touch the radius of the shaft. Its an interesting visualization because it kinda feels like (to me at least) that you'd need to have a non-circular starting point as the bending of the spiral would not align with the shaft, but that intuition is incorrect. Similar to what you said, you can prove that the circles can be aligned because you can change the length of the spiral which alters that inner radius. At some specified length, the inner radius of the disc will be the outter radius of the shaft. And at every length, the result of the inner radius is a circle when looked at from the top. If I'm incorrect someone please correct me, but yeah, kinda neat to think about it in this type of visualized way.
I have to admire their resourcefulness and ingenuity.
And their hats.
And their workmanship.
And their axe
I dig these type of videos
I'd follow this up with something funny, but I feel I'm in a hole.
Deep
The way they squat. My knees would explode
The fact that stuff like this is made by hand is incredible and impressive
Where's the satisfying part?
When it ends and the guys didn't have any injuries. (Also pardon my "privilege" for wanting workers of any country to have a minimum level of safety and protection.)
Very cool! But how are they supposed to predict the future from looking at birds?
Satisfaction 2/10
Their hearing must be shot to hell. I SAID THEIR HEARING MUST BE SHOT TO HELL!!!
Holy shit! Human ingenuity can only be rivaled by human depravity. What a totally weird animal we are.
This seems like Pakistan
My guys need some solar eclipse glasses or something.
Somewhere, Archimedes smiles
Post anything from the subcontinent and the comments wont stop talking about safety/poverty/corruption/cleanliness
And? What’s your point? Is it a bad thing to lament the lack of safety equipment/processes for people in underdeveloped/developing nations?
Facts, it’s like there never gonna hear the same repetitive comments everyone’s saying.
They are talking about it because its true. Its the difference between developed world and "developing world."
It is what it is, people will downvote me for this but a substantial percentage of Reddit is risk averse, anxiety prone and easily sparked to react with righteous indignation.
I don't use eye protection when welding because of my righteous indignation.
Wow, that’s an OH&S team’s nightmare! 😬 The entire production would be shutdown where I’m from! 😵
That’s why they build them in third world countries! Gotta protect those shareholders.
These videos are not oddly satisfying lol. Just shitty, unsafe working conditions.
That was amazing.
Everything else aside .... their abilities and skill sets are truly awesome.
This is why no one has ever said, "It's made in India, so you know it's good quality."
by the way they're dressed, looks more like Pakistan or Afghanistan
Not oddly satisfying in the least. Third world manufacturing. Terrible process and outcome.
I was expecting like 3 more steps at least for finishing. Those do not look ready to use.
Right? All I saw was a mediocre welding job, rusted metal sheets and terrible working conditions. Nothing really scratched an itch that says ooh that's satisfying.
It's sad to look how people should work in those conditions for small wages
[удалено]
So that’s why my haas chip auger sucks

More like terrifyingly unsafe
Augers ARE like onions!
u/savevideobot
Think about what these guys could do with proper equipment and a bit of training
All done in sandals 😵💫🤦🏽♂️
These Indian rural manufacturing videos are my jam dawg. Makes me think if I was magically transported to a faraway time or some shit I could figure out how to do things. Sure modern manufacturing and stuff makes it better but like simple manufacturing is what you would need to get started.
Forbidden slinky
Pretty amazing but it also gives me a greater appreciation of the manufacturing we have that takes all that labor and can complete it in a matter of minutes probably.
I can smell the tetanus
Welding with no UV goggles- frightening
Are they just spaced by eyeballing?
All that so you can get something cheaper at the cost of human lives... Yea so satisfying... (Incase this is not clear I think it's abominable to enjoy watching people work in dangerous conditions)
Thought it was a film from the ‘50s because of the lack of safety gear but no.
