How Mechanic Unimaginable Fixes a Broken Axle Like a Straight Arrow || Double Joint Work #unimaginablefixesbrokenaxle #mechanicrepairedstraightaxle #pkprocess
So many out here with their smart opinions. They do not understand the conditions these people live under. It’s easy to talk. Not that long ago the US made catsup sauce because the meat was just not fresh. Not that long ago the Cuyahoga River caught fire. Not that long ago NY skyscrapers were built by men without any safety. Every nation takes such a path as it grows/matures.
Dicey, but it should work for a while if not heavily loaded. Those welds have hidden inclusions by the look of it, and the lord only knows how the material of the rods will react with the alloy steel of the shaft, and we haven't even touched on the heat stress and the lack of heat treatment after the welds are done. Still, you have to work with what you've got, and these guys are clever machinists. I'd love to see them in a well equipped shop; there wouldn't be much they couldn't tackle. 🙂
Watching these videos makes me think of a couple of things. Sometimes perfection isn't necessary and "good enough" will do. Clearly this repair is something they've done before and suits their purpose and conditions. The second is that I am extremely lucky to live where I do where tools, equipment, materials and replacement parts are readily available. Now when I hear "I have to wait 3 days for a new axel? That's the end of the world!" I can just laugh! Great job guys!
@@raopsepol"have access" dude, i can buy 4 axis milling cnc machine from africa and get shipping. Accesibility isnt concern, money - is. They work on this because its all they can get.
@@andreykotovsky I assume you watched enough pakistani videos to notice not a single torque wrench ever use in any of their works. Don't tell me they cant even afford torque wrench. I don't care what tools they use, but the method. It can be done correctly even without CNC machine. But too bad they still fix things like its 1950s.
Entertaining but should only be considered an emergency repair, especially the welding. Liveleak and Kaotic videos have to start somewhere. These guys are doing the best they know how.
They look like worn-out prehistoric machine shop equipment and so do the machinists, but the fact is the skills and final product seem world-class work. I salute these people and their skills in engineering.🤤🤤
Without preheating the join zone before arc welding (and using the completely wrong type of filler rod) is going to leave the metallurgy around the weld area compromised & weak with very high probability it will again break under heavy load.
@@benjurqunov good point! Bit like the clickbait ones of an old TVset found rusting away in the rice fields that after washing the mud out it works perfectly!
Aesthetically and physically that was some masterful work. However shafts like this need to be heat treated, otherwise it will break again under load. In some regions of the world, sometimes getting a new spart part may be difficult or too expensive, hence the need to reuse and repair with whatever is available. These are talented machinists!! Great job!
But what a masterly job... In a turning shop it is an apprentice's job and in any case he has only wasted time repairing that axle shaft because at the first effort it will break off exactly where the welding was carried out, among other things not even with a basic but rutile electrode which offers less resistance let alone on a hardened material... Unfortunately they are forced to make do but in essence it is a totally useless job... I can confidently say this after over 40 years of working in that metalworking sector.!!!
@@lucarambaldi2731They know what they are doing. Just because you did not see the heat treating process in this video? Doesn't mean the repaired area wasn't heat treated.
Все эти чудеса на самом деле пример неквалифицированной работы и недостатка ресурсов. Это скорее всего Иран или Афган так что вот вам пример, убивать неверных тяжело когда ты сам дикарь
Rudimentario, sencillo y altamente eficiente este trabajo de reparación. Creo que ni un taller computarizado lo hubiera logrado y con ese grado de exactitud, pulcritud, esmero y calidad. FELICITACIONES señores 🎉.
Awesome machine work. These guys are true craftsman. Probably only cost $100 US to fix it. Here it would cost you a fortune for a new axle. Amazing work. Get some safety clothing and footware. Be safe and healthy.
No machinist would be "amazed" and no one not a trained machinist can have a valid opinion because they look without truly seeing. The reason broken axles are replaced in the first world is because those "repairs" are of low quality and safety unlike the third world matters. New axles aren't a "fortune" either. Proper maintenance and repair save lives when a loaded vehicle is at speed on the highway.
If one welded joint is good, two gotta be better. Single weld will fail. Adding a second doubles the chances. These men fix things this way because they have no alternative. Use it up. Make it last. Sometimes life is hard.
It is not logical to compare the quality produced by this ages machine against that of the original part produced from the factory. I admire the skill he has and the method he use to ensure the alignment of the axe.
Lots comment on heat treat and bad welds. People in 3rd world countries spend their money very carefully. I bet these guys know exactly what they're doing and it'll be the best repair the customer can get.
You cant get that kind of quality craftsmanship in thd usa. Those guys will cry about why it can't be done and EPA, and OSHA, AND safety regulations and why it won't work.
Whadda mean? He's got the OSHA approved (quick-toss-one-of-these-in-the box-before-sealing-the-factory-carton) welder peering filter @18:36 keeping his left hand busy. I mean how many times when running a bead you're thinking "gee I wish I had one fewer hand to work with on this job" ??
It is amazing to watch how great these people are!!! If the workplace couldn't supply safety equipment they couldn't afford any. Most times they drink water and then go hungry saving wages to feed the brood and are internally indebted.
Muy bello trabajo , ni se imaginan la complejidad que tiene realizarlo , debido a lo eficaces que son al mostrarlo. Solo una observacion ; Cuando soldan , debiesen poner alguna proteccion para la bancada (Paño inifugo o cuero) para que las chispas no se lo estropeen con el tiempo.
OAL on an axel like that isn't critical. It could be easily + - .180". Said that.. I wonder if this video really depicts axel repair they honestly expect to last if put into service. Or just make a youtube video to make money on.
В этом то и весь цимус , таким приметивным измерительным инструментом работает человек , да и станок похоже не первой молодости , а всё подойдёт ,,тютелька в тютельку " 😊,👍👌👋.
@@benjurqunov It will snap the moment it feels the torque, it's only held by the welding while the central parts will spin in each others as they are inline with the axis of rotation. If there's any sensible way to mend something like this I can think of, will have to drill three or more large holes off axis in each end (instead of one in the center) then using three hardened dowels to connect them so they can bear the torque. but in general these parts are designed to barely withstand the stresses plus some extra safety margin when they break they need to be replaced.
With the spigot left in the middle 30% of original thickness has gone it’s a quick fix but how long before it goes again is anyone’s guess Good repair only time will tell
Agree, but normally these axles (though this has failed) are designed to withstand way above loads trucks (lorries) are designed to carry. But given the antiquated machine shop equipment the performance of the workers is amazing; for that, I salute them🤗
Yes, your comment is quite understandable as to your poorer appreciation of the subject matter - that is the "axle repair " job. However, these are those equipment that your forefathers left behind in places like India or Sri Lanka.
@@christopherkahandaliyanage2473 I don’t have poorer appreciation at all l respect given the shite equipment that man has too work on he has a great knowledge of machining but sadly the fact remains with a spigot in the middle 30%of the strength is missing. And for you knowledge an imagineer is a joke the guy clearly knows what he’s doing respect to him . My fore fathers were never out there !!
These guys are awesome. I don't think that people fully understand what's going on here. It's one thing to do repairs but when they are rebuilding a drive shaft like this is on a totally different planet as far as welding and making the shaft true to size and balance. Unbelievable. They don't have any high priced equipment like say an American mechanic would have. Done by hand gives this a hole new beginning. Great job by professionals that are all ON the JOBE TRAINED !!!!!!!!
not sure what's unimaginable about it, but I do love that in every video the only cutting tools are cemented carbide. I've not seen one time where any insert tools are used.
Pakistani Home made industry and engineering is unbelievable and perfect homemade engineering products better than Indian automation and foreign in investing.
This was a great job. Given the non-availability and astronomical cost of that axle, these guys are necessary in the cogs of their industry. How long it lasts, and how much weight the axle will take, is anyone's guess. However, for an even better job, welding-rods compatible with the axle metal has to be used. Then the welds must be stress-relieved. This is a gradual heating and cooling of the welds that takes many hours. This would cause the molecules of the metals to arrange themselves, so that everything melds into one piece of metal. When this happens there will be no weak point likely to give way under stress. Obviously, their method is faster and cost-effective ! Trinidad & Tobago. West Indies.
