I wouldve done a better job with a grinder and stick welder, ive done it few times by now and the welded part hasnt failed ever. No clue why the hell would they put that thread in there, to weaken it even more?
Whatever the diameter of that threaded end, the strength will be about the same as an equivalent sized bolt? Nowhere near what the original solid splined bar was.
@@mihkus My father would have silver soldered something like that instead of arc welding. The silver would have flowed around all the threads a made a reasonably strong bond

Removed the heat treat, and joined so so. I understand though, use what you got. But i would have drilled some small holes through both pieces and welded that too. Then givin it a reheat , oil quench, temper to straw, to at least try to get a bit back. And release some stresses. Anyway. Nice work on doing what you have too and gittin her done. Hopefully it lasts till the better replacement is found.
Very good work. I like how you repair things, and not just throw them away. In Norway this axle would been scrapped, and the owner would need to buy a new (and very expencive) axle. Greetings from Norway.

The job looked great when finished, but could never be as strong as a new replacement. Also, I feel that (if you are going to weld the job whilst it's still in the Lathe), it would be better to place the Earth Electrode directly onto the shaft being turned.

shouldnt weld loke that using the lathe as a ground wat happens is that the current goes through the bearings of the lathe partly welding the balls to the races and wearing them out verry rapidly if you do need to weld on a lathe make sure the groundstrap is on the piece youre welding not on the lathe itself seen a few of this exact repair where they wittle down the shaft to half its size fit a new piece with a hole over it and weld it up , they done it a few time so it aparently works , i just wonder for how long as theres a pretty big twisting force on a halfshaft
He may have put the return clamp on the lathe throat. I once did a similar emergency repair for a motorhome with a damaged spline after a bearing retainer failed letting the axle walk. Instead of threading the coupling I did a full 0.002 interference fit and pressed the undersized replacement spline onto the reduced spigot using a 40 ton press with the spline heated to almost red. Then finish welded, cut and heat treated the entire tail back to original hardness. Not sure how long it lasted, but it got him mobile again for about half a days work.
Title say’s experiment and dudes just showing off his 3rd world skills making a better video . But ya kinda unnecessary if it was to fix something that was getting welded anyways .
@@williamallen7836 That’s where the welds come in. And depending on left or right hand threads either way forward or reverse there’s a chance of it backing out. It won’t back out all the way as the axel is in the hub but with no welds I’m sure stuff will break down Waller out and such.
@@dustyak79I think the best solution would be a hole cut perpendicular to the splines going through both pieces of metal and a pin run through the hole, welded at the ends of course. Strongest joint would probably be threaded(with threadlocker added), welded at both ends, and having a dowel pin run through it(also welded)
good effort and excellent skills.there is too much pressure on the excels due to torque .these kind of alterations should only be done in case of extreme situation when parts are not available.normaly not recomended due to high risk factor.
very well done. The non use of cutting oil did bother me but not near as bad as not covering the ways on the lathe before welding. Why be so hard on some pretty nice equipment. But no doubt a solid fix
Interesting fix. But, that's all soft metal. He doesn't seem to have a way to heat treat anything for strength. But, good enough for a roadside repair, I guess?

The most fun part is the assembly can be screwed to precise length before welding. BTW as the threads mostly locate the threaded joint could be of much smaller diameter where deeper weld penetration is desired.

А сколько эта потрясающая работа проработает? У нас на работе тоже пытались подобными подделками ремонтировать оборудование, пока не начали лететь все насосы и до начальства дошло что скоро зима и в отопительный сезон нечем будет работать и станция встанет. И наконец впервые за 5 лет купили заводские запчасти, и насосы заработали.
Why does he ruin the heat treatment of the part before cutting it? I know it will soften it and make it easier to lathe but he's got carbide tooling which is more then capable of cutting into the shaft without softening it first. But I guess the welding would have done more damage than the torch
The interrupted cut on the hardened surface was instantly too much for the tooling. Note that subsequent cuts that left the surface blue. Something is very wrong with the feed/speed, tool angle and edge. Chips might end up blue with a heavy cut, but not the work. I don't know the alloy, but that may have left the surface work hardened and made each subsequent cut harder on the abused edge. If the original part with a properly hardened surface failed, the replacement is going to have a very short life.
Кто-нибудь, расскажите мне, зачем он там нарезал резьбу, если потом все равно заваривал? Работать будет только сварное соединение. Лучше бы он сделал гладкие поверхности и с горячей посадкой одно надел на другое - больше толку было бы.
This was a ton of machine work just to put a horrible weld on it in the end. They could have achieved the same level of performance without the threads and there was no need to weaken the spline by Drilling out so much of it just to thread it. But I still love these videos on my days off.
Guess where it's going to break next. Hint - the axle strength has been reduced by removing all that metal so the failure point is where the reduced section meets the original section.
My first guess was Habeeb to weld on it to get the length & shape back. Then turned back to size finishing the splines back into the shaft with an angle grinder. Don't forget to throw the part on the dirt floor after every step.

The torch anneals the metal for cutting (removes the heat treating 'hardening') and the welded finished work is a mixture of metals that can't be heat treated in any meaningful way, so it's left partly annealed. You could never get away with this in the US or a developed country. I don't imagine the end of that drive shaft was destroyed quietly either. Videos like this display a waste of perfectly good machining skill. This might be 'cost effective' in India, but this would far exceed the cost of a new drive shaft in the US, custom lathe work ain't cheap here.

судя по тому как они относятся к станкам дефицита запчастей у нет .
This kind of repair has a higher tensile strength, but the torsional resistance of only the thin welded surface is not enough.

The torch anneals the metal for cutting (removes the heat treating 'hardening') and the welded finished work is a mixture of metals that can't be heat treated in any meaningful way, so it's left partly annealed.
