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.

Clearly this repair is something they've done before and suits their purpose and conditions.

@@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.

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.
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. 🙂
I was just thinking the same thing. I'm a mechanic tho, not a welder. I was thinking the porosity of those welds has to be off the chart. It looks like they kinda just super glued it together. But technically the axel only has to tolerate torque or twisting force. I think I would have gone with a threaded design that his press fit. Heat the female side of the socket, and freeze the male side, thread together and let cool, and avoid the welds all together. Maybe even counter the threads so that they never losen on both ends at the same time. Or.. have both threads facing tight while the axel rotates forward. Because a vehicle that uses an axel like that prolly won't be moving backwards that often, and if it does, not very fast, so the threads should always be tight.
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.
Theres just no way thats going to hold. The metal was clearly hardened. It fractured rather than twisted. No matter what filler you use, the shaft will be weakened in the heat effected zone and just twist right off again. Obviously, hes got some skills. I have to assume that he knows it wont hold, but the custimer gets what the customer wants. I guess if you need the truck and cant get a replacemeny, you do what you gotta do and just try to baby it.
we did exactly what he did broke an axle on a 48 buick out in the bush , the mechanic got another axel that was too short so he lathed a dowel on one and a hole on the other and welded them the same way while in the lathe preheated the axle before welding it , that axle is still in the buick we grossed 4 ton pulling a caravan and did a 2000 miles round trip

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.
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.
Maybe not as strong as a new one, but when a new one costs 100 times more than repairing this one, then it probably is worth it. Remember, labor is cheap many places. Yoy gotta give it to them, they are quite good at what they do here. My personal opinion is that this is an art that is pretty much forgotten in the west as we would rather replace it outright. No questions asked.
@@pr00009 South Asia has been a repair not replace culture for decades. Yes a replacement is ideal but with costs of repair so low it’s more viable for them to repair many times over before the coming close the cost of a new part. A thought process outside your understanding 👌
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.
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.
Shieldes welding is the wrong process for higher carbon steels. You need to use MMA that was used with a hugh Nickel like INCINEL or a Low-Hydrogen. Mag or Tig would be the wrong process by far.
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.
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!
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🤗
@@benjurqunov Thanks, I didn't know that. When I was much younger I had experience with trying to fix such an axle, it broke! There at the time was a very old machinist I knew (90 years old) he turned the pieces down like the video and welded it and it held! He just really knew metal and metalurgy.
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 !!!!!!!!
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" ??
Awesome job!!! It’s superb and also effective!! P.S. Loads of people commenting “oh it’ll break..” Ok, but how about this axle is for another type of “load”?? Like, less charge/weight?? It’s still useful, properly fixed!! The axle maybe it’s not going to end up in the same place, they fixed it just because the use they can give is for another vehicle/load Quit being cringy..
It constantly amazes me. You weld on top of your lathe. Understand using that process to watch for "straight(ish)" while assembling patch. Grant you that part. My point is look at the surfaces that welding splatter is destroying. Flat bed ways now have pits to collect grit so that every time it is repositioned, the grit grinds away at the 0.005 clearance. What about the weld splatter stuck in the threaded feed screws. How much wear is that creating in the feed accuracy. If you have access to such a machine and have learned the art of machining, you should at least take enough pride to protect your tool. Forget the fact of the non-existent steel toed safety sandals. 🤣
Yeah and I didn't see a ground on the shaft so weld current will pass through the bearings. On the plus side, these guys seem to own the only welding hood in existence in Pakistan!! I've seen a lot worse from these shops and if these guys are lucky, maybe it lasts a few months in the massively overload truck, it's probably going back into, . And maybe their luck continues so when it does break on a crowded street, it doesn't wreck, running over and killing some poor unsuspecting family.
@@bobsnabby2298 Yes, Kurtis from Australia protects lathe parts with flame retardant cloth. However, this is not the only complaint against these guys. They do not follow any rules or procedures. Their result is likes for the video.
@@mightyluv Oh. it's going to be far from perfect!! On the plus side, assuming this is from a pretty good sized truck, it will probably be spinning less that 500 rpm at 45-50mph. I think the biggest issue is related to torque it has to handle. Th type of steel it is and the rod being used are likely a bit of a mismatch. Every Pakistani welding video I have ever seen uses 6013. I think in Pakistani, "6013". means welding rod. And you can be sure that there is no heat treating that will happen! No need for that because it got hot wen they welded it!! Looking at the break and how it behaved in the lathe, the original shaft was very hard steel. I would be quite surprised if they achieved 40% of the original strength. But it looks OK and in this part of the world, if it looks the same, it is the same.
The main message I usually get from these videos is - we should all just skip the high quality metallurgy and forging processes and just build things like these guys do. Throw away the work benches as well and work off of the ground. That's the way the real genius do it.
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.
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.
I mean it looks good. But now how did you weld the parts beneath the surface, where you doweled in? You definitely only half the strength there now. Good luck to the customer
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 !!
@6:36 Eureka! I knew there just had to be cutting oil SOMEWHERE in that shop! Must be really expensive though as it only comes out for the steady rest..
Pakistani Home made industry and engineering is unbelievable and perfect homemade engineering products better than Indian automation and foreign in investing.
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.
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.🤤🤤

Ok, but how about this axle is for another type of “load”?? Like, less charge/weight??
It’s still useful, properly fixed!!
The axle maybe it’s not going to end up in the same place, they fixed it just because the use they can give is for another vehicle/load
Quit being cringy..
Ну во первых это не на долго, чисто стоб доехать до гаража, не более. Во вторых - нужно это место прогреть в печи, чтобы снять напряжения швов.
Вентилятор крутить этим валом только 😊

It constantly amazes me. You weld on top of your lathe. Understand using that process to watch for "straight(ish)" while assembling patch. Grant you that part. My point is look at the surfaces that welding splatter is destroying. Flat bed ways now have pits to collect grit so that every time it is repositioned, the grit grinds away at the 0.005 clearance. What about the weld splatter stuck in the threaded feed screws. How much wear is that creating in the feed accuracy. If you have access to such a machine and have learned the art of machining, you should at least take enough pride to protect your tool. Forget the fact of the non-existent steel toed safety sandals. 🤣
Don't worry professionals like CEE from Australia do that too. It's just all about covering things up.
Yeah and I didn't see a ground on the shaft so weld current will pass through the bearings.
On the plus side, these guys seem to own the only welding hood in existence in Pakistan!!
I've seen a lot worse from these shops and if these guys are lucky, maybe it lasts a few months in the massively overload truck, it's probably going back into, . And maybe their luck continues so when it does break on a crowded street, it doesn't wreck, running over and killing some poor unsuspecting family.
@@bobsnabby2298 Yes, Kurtis from Australia protects lathe parts with flame retardant cloth. However, this is not the only complaint against these guys. They do not follow any rules or procedures. Their result is likes for the video.
I questioned the accurate concentricity of the patch piece stubs using the 4-jaw chuck.
@@mightyluv Oh. it's going to be far from perfect!! On the plus side, assuming this is from a pretty good sized truck, it will probably be spinning less that 500 rpm at 45-50mph.
I think the biggest issue is related to torque it has to handle. Th type of steel it is and the rod being used are likely a bit of a mismatch. Every Pakistani welding video I have ever seen uses 6013. I think in Pakistani, "6013". means welding rod. And you can be sure that there is no heat treating that will happen! No need for that because it got hot wen they welded it!!
Looking at the break and how it behaved in the lathe, the original shaft was very hard steel. I would be quite surprised if they achieved 40% of the original strength. But it looks OK and in this part of the world, if it looks the same, it is the same.
Уважение к этим парням!
The precise measuring and the shortage on oil.
Так вот как точные измерения делают? А я знал😂. А в универе микрометры, штангели вот как надо.
микрометры и прочая фигня - это для лохов…
Они использовали микрометр там где это необходимо. Смотри видео!
Excelente trabajo.....muy profesional....los detalles perfectos...Aplausos.
Кроме резьбовых резцов походу никаких других нету Возьми просто отрезной резец и отрежь
The main message I usually get from these videos is - we should all just skip the high quality metallurgy and forging processes and just build things like these guys do.
Throw away the work benches as well and work off of the ground.
That's the way the real genius do it.
Excelente travajo saludos desde panamá 👏👌🇵🇦💯x💯👀👊🙋♂️
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 !

Um trabalho bem eficaz muito profissional parabéns 👍💯
Thats a brilliant repair to be fair 👏🏼 👍 👍
Wow nice work my friend. Very good work.
Are the dowel holes too big?
Don't you love the eye protection, machine guarding and steel toed safety shoes?
Welding on the lathe machine, where did he ground the part. I wonder what he did to the bearings on the lathe spindle.
😂😢😮
Хороший мастер, 👍
только полуось плохая
Bravo, great work, I would have made the break point a little bigger, but well done, thank you for the video, from Canada
😃¡Son unos genios!👍🇲🇽.Esta no es la presicion de las maquinas, sino de los maestros que las trabajan.👍
Great job for doing this with very few tools! It may not have the same mechanical capability, but it should work for everyday use.
Just watched this with Ray Charles and Stevie Wonder, we all agree it is a fantastic chocolate cake recipe.
These are the guys to use when you want that Ford nine inch shortened for that gasser your building.
@BEDavisBrown.....😁
No, no they're not.
Not w/ MY life on it.
@@rippn6124 If your racing a gasser your already living on borrowed time, especially one that's blown and injected.
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.
I wonder how accurate they are in these kind of repairs.
Завораживает эта работа профессионала.
Цементація? Повєрхностная закалкв? Нє, нє слишалі.
Esté es un trabajo de maestro un fuerte saludo a la audiencia 👍🙏🤝🇨🇺👈
I mean it looks good. But now how did you weld the parts beneath the surface, where you doweled in? You definitely only half the strength there now. Good luck to the customer
Half strength only if assuming perfect welding. But that welding doesn't look like high quality.
love it when they drop things on the ground
Based on the audio, the Jawas are doing the hard work.
He’s what we called in our tool Tool Room an imagineer looking at that lathe it gotta be 70 years old at least
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 !!
Как он круто обращается с рулеткой!!!!
Waooo, excellent work bro
Thanks bro…😊
После каждого слоя сварки,
нужно зачищать абразивным кругом до устранения пор.
А варить нужно нержавеющим электродом (зелёным)
🤔
Не обязательно нержавейкой. На горячий шов сразу грунтовку или любую краску. И век не будет корозии
выкинуть надо эту полуось а не варить
И обмотать синей изолентой.
What's the black stuff they are putting on the machined area at the end of the video?
...Hope
Excelente. Parabéns

@6:36 Eureka! I knew there just had to be cutting oil SOMEWHERE in that shop! Must be really expensive though as it only comes out for the steady rest..
His weld last along time he is a master machine operator
May Allah bless him and his family and everyone in his shop
What should not be done.
It will not last.
What's fun is work he does.
And it typically breaks, mounted in a bus, when loaded with 80 persons plus luggage while the bus is permitted to carry 35 persons.
They make these fantistic repair videos for youtube money.
They don't expect this repair to last.
why so negative??@@orangmakan
Pakistani Home made industry and engineering is unbelievable and perfect homemade engineering products better than Indian automation and foreign in investing.

Hardened steel axle and they just weld it with normal welding wire😅😅 this will snap right off.
Выглядит надёжно, но до первого применения!
trabalho de cabra macho! estamos por cá ,Brasil.
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.
Excellent 👌 work 👍
Made skills, very impressive.
Bravooo brother..👏👏
always use the guessometer tape never fails.
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.🤤🤤
Варили и у нас однажды сломанную полуось на самосвале МАН-41 8х4. Ну что сказать... эвакуация гружёного самосвала из песчаного карьера оказалась дороже, чем покупка новой полуоси.
How did you balance it
how long it can be use??
Probably the strongest part of the axle shaft
