He wants to weld free

@@octymocty132 GUYS 🤣🤣🤣🤣🤣

is there a special type of welding method for forged parts?

No nie wiem czy byłbyś szczęśliwy jakbyś miał zestawy kołowe w lokomotywie naprawiane tą metodą ? :-)

There's a reason why you never seen it .... it doesn't work , it's gonna rip apart after the first 2 weeks .

Not really a grate idear if you have powerfull engines with lots of torque changes. I hope this one is for something unimportand.
1. Crankshaft are forged wich means they lose stability if heattreated with a torchflame
2. Crankshaft are balanced on rotation wich is necesary to not brake at 3000 - 5000 rpm. Welding it together will unbalance it.
3. every Crank on the shaft has a precise location. if it out of place the engine piston will not be at the right position when the fuel is ignited wich can cause futher damage to the engine. And will make it run dirty.
But I am sure they just cant get or afford a new one, so it is the only way to go.

@@randomtux1234 Yes DO NOT WELD forged parts. You will take its strength be reheating.

How long will that last? If an original crankshaft brakes, a welded one can't take the strain. I once had my tractors clutch case welded, it did not last long. The weld itself is stronger, but the joining pieces are weak.

@@hanspeterraatz4928 Well it has a spigot and the front section was pressed on - probably strong enough for what it has to do. Must be strong enough otherwise he would have only ever done 1 and no one would bother with it again, unless they like pulling motors apart to regularly change crankshafts.

@@hanspeterraatz4928 I think if this were the first time he's repaired like this you might have a point. Clearly he's done this successfully a hundred etc times and this is repeat business.

Actually he's a master machinist.. Engineers design, machinists repair!

But the weld cant be through, so the joint metal is weak at that point.

Looks good on the outside ,but what about the inside?

@@hanspeterraatz4928 магнитно-порошковый дефектоскоп покажет, или вихре-токовый.

@@hanspeterraatz4928 If you had watched the WHOLE welding process, you would have seen that the ROOT passes were just as good and had NO inclusions. The slag just peeled off which shows good welding techniques and settings. Unless he is the only repair shop, the work must be good for people to use him. You have to bear in mind that these 3 rd World Countries do not have easy access to factory rebuilds or even perhaps spare parts, so everything is Make Do and Mend culture.

@@hanspeterraatz4928 After watching this man’s skill and the technique he used I’d bet money he’s repaired thousands of crankshafts, I’m sure he knows a lot more than me and you on how to do this type of repair successfully.

@@georg1875 They don't seem to bother with preheat.
Also there seems a stack of identical cranks waiting for repair so maybe the original isn't strong enough for the job.

exactly, I'm farm born and raised, the whole of my Dads side of the family is mechanically inclined, my other Grandad was a painter and decorator, so I can repair/ build and paint the machine. I've been doing this since i was about 12 when I changed the first cylinder head gasket on a car we trashed round the fields. At that time in school it was just when computers got into home life. Lots of my friends laughed at me getting covered in oil and grease after school. The big problem they couldn't figure out was if somebody cut the plug off their computer, they couldn't fix it they needed me that could rewire it! society went all computer and away from mechanical type guys. Now they finally realized they need some more guys to replace us as we get older ,as a computer can't do everything.

@@Mekzuc91 not can’t , but will not , that’s why it broke after the previous repair. If you are a tradesman in this field you will understand.

looking at the failure it looks like a failure caused by vibration ( that's why engines have harmonic balancers ) if I'm right and they manage to weld it accurately and balance it, it's going to probably be as good as a brand new crankshaft it could even be better, it just depends on the care taken by the original manufacturer,

What most are missing from the video is that he is actually joining two different cranks together to make one....The short section of crank is sheared at the counterweight and the long section was cut off at the counterweight. amazing work for sure

He's probably making it into a bomb.

they're far from craftsmen and engineers. These guys are shop workers who have repeatable skills.

Thats far far away from amazing skills, there are so much failures that even to lazy to describe all. For example there was no pre-heat before welding, no balance, it spins in waves, ect, ect. Was fun to look, but I don’t even think attempt to use it myself or suggest for someone. It’s price is same as was before repair - scrap-metal. Normal crank is way much precise thing.

@@antanaslomsargis8952 I hear what you are saying, but looking at all the crank shafts sitting for repair he must have a good trade, remember parts are not available in a lot of countries particularly the poorer ones, also they are when available prohibitively expensive. I found his checks although not as precise as in a factory setting, he was very particular about alignment of the journals so I cannot fault him for doing the best with what he has available to him.

Most likely the engine will be re-task with something that puts far less stress on it than what broke it in the first place, like running a sawmill or a generator instead of being in a delivery truck or whatever it was that broke this in the first place.
If they try to use it for the same application it'll break in a fraction of the time it originally did and I have the feeling these guy's know that.
