First world countries are not ‘lucky’ to be working in better and safer conditions.

I used to make air vessels professionally. Each was hydrostatically tested to more than twice their max operating pressure. The really big ones would have their joints checked by x-ray. Coded welders, critically stored rods, low hydrogen steel.
We use submerged arc welding for our high pressure vessels. Each step has to be documented, each layer will be inspected by germanys TÜV Rheinland. I feel sorry for the victims of any Druckkesselzerknall (i will not even try to translate this!).
My dad worked on fuel tanks. He did this all through the height of summer in Western Australia. He was about 30years old otherwise he never could have done it, But I digress, because they were fuel tanks the weld joints had to be x-rayed, now as I think about his suffering doing this job, I have a new respect for his work. Day in day out very very hot in summer very very cold in winter and not much to show for it except a weekly wage for a gruelling job and a son who didn't see the hardships he went through.
Very hard workers with the ability to create a tank with their talented hands. It looks like the 60 gallon air compressor I bought from Lowes home improvement center
You'd best hope it was not that tank. Steel is of questionable origins, and appears to have a weld repair in it. Have you ever seen the damage one of these tanks does when it explodes?
This the first time I ever see a Weldor in these videos that has a proper welding hood and gloves and knows what he's doing and making solid beads instead of that tack shit they do over there
In Malaysia, these are called pressure vessels. They can only be done by factories licensed by the Department of Occupational Safety and Health (aka DOSH). All pressure vessels like this follow ASME Code Sect VIII Div I and can only be done by certified welders in licensed factories. Each are tested to at least 1.3 times their allowable pressure. (1.5 to 2 is usual). Non Destructive Testing (NDT) such as Dye Pen Test (DPT) and Radiography on the welds may be done. We do this all the time but never like what is shown in this video. All our workers wear PPE. That's the law. In this video I suspect injuries such as cuts are a frequent occurrence. One never handle the edges of a freshly cut steel with bare hands. They are very sharp!
Antiquated machinery with a certain justifiably questionable durability and reliability but realistic every effort by these guys is required to maintain an effective fabrication the entire disturbing experience requires some forgiveness and respect for each process of build is a testament to their adaptability ingenuity inventiveness and the skills to achieve their goals

Nice rusty internals, welds chilled with water, potential weld failures. Razor sharp edges no gloves. Welding with sandles... Debri left inside... hope you want you airtools to last a while... Quality.
They used a tiny single cylinder compressor to test the tank for leaks. Don't think it could develop enough pressure to actually proof test it. Besides, it would take forever for that little compressor to fill that large of a tank. Also, no condensate drain in bottom of tank. I wonder how many have lost fingers or toes handling those steel sheets.
Denny Poole, I can't believe that is all there was to it, and they had the audacity to show it. A compressed air tank is dangerous and a proper test a legal requirement.

Why do they never prepare the surfaces they are welding, a wire brush to rid the surface of rust (always present in these videos, they even paint straight over rust in most of them) wouldn't cost too much, would it?
@@blanchae mate, they cannot even buy their employees any safety equipment, no less decent equipment so I'm not convinced they will be buying fancy welding rods. Cheap and nasty is the name of the game.
After welding do not throw water in the weld because the plate when very hot and wet catches a trempe and is very hard conducive to cracks which is dangerous for an air storage tank, let it cool first without throwing water, more the work of you guys is very good, always follow here from Brazil, I also like to see how you guys put your children to learn a trade from a young age, this is very good.
looks like they missed a page or two on pressure vessel testing , NDT, coded welding good practices, safety at work, design of a pressure vessel, as the lap joint left inside is a perfect place for corrosion to start,

Bro, they have a 30k dollar lathe...they can afford a mig. The only reason they don't use them is because their electricity is rationed and they think sticks use less... somehow...avg IQ 80 tho.
Those men work for their living as I watched with great respect, but that guy doing the leg assembly - welding without eye protection - how long will his vision last during his life?
I would be very worried having one of these untested pressure cylinder's in a workshop. Stick welded, contaminated welding. No X Ray of the quality of the welding. If one was to blow up it can and most probably will kill someone. One Dodgy coat of blue paint hides everything.
Skill of the persons are very good but there is no cleaning . inside outside rust and dust is everywhere...even paint is done without cleaning the surface...
I've been watching these videos, and I keep wondering why do these men wear house slippers to work around all this metal? Has anyone lost any toes or feet? They should be wearing work boots steal tip toes at least.
But why these dudes work in dirt and mud on sandals!!??? I mean, are they happy? Do they know the difference between good and bad?? I simply don't understand
A humble question: Why the overkill in steel plate thickness? Is that to add extra safety margin just for (lack of trust) the welders variable skill levels? For tensile strength it’s not required. Even if the steel quality is crappy. Kind regards Anders Sweden Retired mechanical engineer
May i bounce some points off you?... if you don't mind. The first assumption i have would be that they use what is easily available. The second guess is that they are using what seems to be AC transformer welders, these have very limited settings... for example I own one that can weld at 50amp or 90amp or 130 Amp or 200 Amp. Nothing in-between. They probably try use a thickness that best limits easy burn through from the limited welding current settings. If a tank of this size were properly engineered, 5mm plate ( of good quality) would probably be the needed thickness, and it looks to me like that is about 5mm. I agree it would not need that much to achieve the tensile requirements.. but depending on the construction code... safety factor and corrosion allowance usually leaves you with around 5mm for a tank of that diameter at about 1100kpa design, (minimum thickness calculations as layed out by the code...ie Asme 8.1 or AD2000 etc). It's seldom piston compressors will push 1100kpa but it's the most common compressor tank in the west. Furthermore the tanks need to be structurally stable.. they allowed limited bulging and flexing under hydro test.I'm intruged... what nature of engineering did you primarily work in? I currently own a pressure equipment inspection company and am completing my engineering studies slowly as i get a chance(I have 1 semester left). I first built industrial boilers and qualified as a welder and then moved into project management in petroleum storage and handling prior to going into Inspection. Always keen to learn from retired folks insight.
@@POTGIETERDAVID hi Thx for posting. You may have a point as regards the welder. I don’t remember what they used but with fixed presets as you mentioned one has less options left than choosing a pin that welds hotter (or changing thickness which is unnecessary expensive and heavy or too weak). As regards structural stability there is no physical shape that is more stable than a sphere. No 2 after that is a shape like a barrel with a half sphere at each end and no 3 a compressor tank shape. These shapes are extremely strong resisting torsion and bending. The plate thickness determines the resistance against denting (with and without internal pressure). So the structural integrity would not be the strength issue one has to address primarily. Or secondary. Steel quality and thickness + weld quality together with vibrations from the motor affects much more. I was working for a multi national company manufacturing trucks for light to heavy haulage. We designed and produced everything on the trucks chassis except some minor parts like alternators, pneumatic brake valves and electrical wires etc. We delivered detailed instructions for fitting body work on the chassis and as an example when fitting big tanks on the chassis frame one would have to add an auxiliary frame and very special brackets between truck chassis and the tank due to the extreme rigidity of tanks. Good luck with your study and business! Kind regards Anders
In all these videos, there is a certain level of base ingenuity, and I do respect that. However, their shop practices are horrifying. People welding without gloves or mask, in flip flops. Or carrying huge pieces of steel... again, in flip flops... So many places where you see a really nasty accident just waiting to happen. I wonder how much of our goods are made this way.
