How Hydraulic Cylinder are Made | Hydraulic Cylinder Manufacturing Process | DIY Hydraulic Cylinder 

Да если вообще догонят😂😂😂.

Cars are easy, we are trying to get to space.

It probably normalized for easier cutting. The rest is harden so it would not bend.

Not the best in the world at all, no quality, no safety every thing is covered in dirt most things are put together with a hammer nothing is clean, people work on the floor. Cheap and nasty.

I doubt that.

@@panza. I doubt that guy at the welder would get fired. You can see he is young and inexperienced. He actually came in shop in leather shoe! That's big no, no in Pakistan. We all know that main PPE piece of every good Pakistani worker are slippers! He even dared to wear real welding gloves. That minimalist cardboard mask would not help him. Very unpleasant conversation with the boss awaits him. 🤣🤣🤣

я тоже обратил внимание обычно они в шлепках работают,даже акумуляторы

youre a complete idiot, these are absolutely hydraulic cylinders. The wall thickness is very typical for cylinders in excavators and farm machinery. As for the welds, arc welding has better penetration than mig or tig in most cases and is fine in this application. If anything welding on a pneumatic cylinder has to be better than on a hydraulic cylinder due to having to seal gas leaks rather than thick hydraulic oil. Don't comment when you don't know what youre talking about.

@@kitramshaw5447 I was not refiring to the method of welding but the lack of preparation, no bevels all butt welds and they have a cushion on both ends, something not typically seen on hydraulic cylinders. I may not be as smart as you are but I am respectful at least.

@@thepubliceye Typically what would be the walk thickness for a pneumatic tube? I work with seals but not so much the cylinder itself. I noticed the piston u-cups seemed to urethane which would seem a little aggressive for a pneumatic application. This is a sincere question.

@@NESMasochist I agree you are correct, so it looks as though they used what they could get, I guess it's a very poor hydraulic cylinder.

@@thepubliceye I give them kudos for the fairly quick turnaround in making a cylinder but, just from I know that it doesn't look like it would last very long. The surface finish would rip those seals apart.

Man , cuelga un vídeo tuyo , ahí se ve la diferencia , ellos le dan valor agregado a la materia prima i así se aprende , yo pienso sus hijos lo realizarán en otro nivel

So that it can be machined, otherwise the metal is too hard.

Может, как-то обработана была? Впрочем зеркалу тоже хана.

Там саму трубу быстрее давлением порвет

no

So dumb

No importa como esté el taller si ellos saben lo que están asiendo en ese país no asen falta robots ellos reciclan todo o lo reparan.

you want to kill yourself?

These things will kill someone. He destroyed the heat treatment on that rod with the torch. That entire Cylinder is compromised simply because of that but I see many other issues that are absolutely life-threatening. Imagine that cylinder is holding up several tons and the rod snaps in half because the carefully heat treated steel has been softened with a blow torch to god knows what strength. Or the seals blow and you suddenly lose pressure and your excavator arm comes crashing down because they used a rusty pipe full of dirt instead of a honed precision pipe. Or that weld breaks on the end cap shooting it across the room with 5000 psi. (5000 psi x 5sqin = 25000 lbs of force or roughly as much as a 50 BMG bullet).

​@@excitedbox5705 se fosse nos EUA seria difícil ver alguém fabricando mesmo tendo bastante recurso agora eu duvido alguém ser tão criativo igual os países de 3 mundo onde se cria homens fortes

@@excitedbox5705 And you should not damage the rod by rolling it against steel and ground or put it in lathe chuck without aluminium covering rod. Worst was when using lathe as a milling machine, he fasten rod with screw. Now there is screw mark on the rod. It doesn't take much to break that surface and then leaky leak. When doing thread in lathe, you should use some kind of a lubrication. Your tool will last longer. We have different standards.

@@excitedbox5705why’d he use that torch anyway?

А какой? тебеж какой втюхают, такой и поставишь.

Так и они и так дунули. До, во время и после, да еще видимо и в перерывах)) куда уж больше-то)

Luke, your boss used clichés and you are taking that literally for a place in a third-world country where labor is super cheap and these men worked their asses off to produce a product equal to or better than what your boss produced at a much higher cost per unit. Go take your clean shop somewhere else!!!

My shop in America doesn't look much better 😂 I keep my stuff clean and organized but no one else does

Well technically you can buy cylinder tube stock that is already honed, but I doubt this is it

it'll polish itself up in service, haha

@@robbiemckinnon7901just noticed it doesnt even have wear bands

If they make it to last, they will be out of a job. 😄
