All the heat cycles from the welding have compromised any original heat treatment. The overall strength is likely to be less than half the original strength. I give it two weeks.
I wouldn't drive with that shit. lol but hey when you got to do what you got to do, I guess make it work.
Heat treatment is not a rocket science for these people. These repairs must have gone through such procedures.
it's a truck spindle...it is not "heat treated"... this is a textbook wide root weld... welding was literally invented for this purpose
Они эту процедуру не первый раз выполняет и не последний раз
And of course loading the vehicle 5x over it's designed capacity has nothing to do with the breakage.....🙄
I have great respect for these hardworking people You can repair almost anything, but not this part that concerns traffic safety. You put people's lives in danger.
In that culture, none of that matters.
5рваав. Ааа а рр🎉😅 5:52 5:53
at least its not jb weld, but yea that thing F@$5all strength
@@WardDorrityqqqjX😊
well if it was heat treated and annealed after the fact it might hold up.. but man im not so sure i would ever trust it ...looks like a steering knuckle too.. poor nations got ta do what they need to.. maybe all our bombing the entire middle east was not so smart
If truckwill be overloaded again, the spindle will break in the very same section. Any welding is weaker than the two steel compositions, it is a superior quality steel for the spindle production. Conclusion: it will break again soon in the same section.
Wrong. It will break on one side of the weld or the other. As they are different hardness metals the weld in this case is softer and a bit more flexible. It will be put on an overloaded truck and it will break. But most likely on the outboard side of the weld. Also never mind repairing the beat up threads on the end of the spindle. Nothing to see there at all
@@martinswiney2192 makes for a great youtube video... :)
if you actually weld you'd know that the weld will be stronger than the base... only an overload will break this repair which is apart of their culture... the repair is proper... the client will still choose to overload it
@@LexusGX460-OFF-ROAD A welding never breaks. Metal breaks near the welding,, în the thermal influenced metalic zone.
Sorry, but you are sooo wrong. The weld is stronger than the adjacent metal..😏
I’d really like to if and how long that spindle holds up for. Regardless of this or that you definitely have to give the man some credit for trying to repair it for what he has to work with. Quite impressive honestly.
still going in 2023 august.
je cpmprend votre point de vue mes j`espéré que vous n`acheter aucune pièce de rechange qui vien de la chine
Fantastically resourceful and skilled repair. The one thing that always worries me when welding takes place in the lathe is where is the earth clamp? If it's just placed on the bed either all or some of the current will be passing through the headstock bearings which will drastically shorten their working life and accuracy.
The bearings will arc and be destroyed. They dont care. They have been told many times and refuse to learn.
You call it resourceful repair and worry about lathe bearings? Good joke 😅
Thanks for the info
Bonjour heureusement vos camions de roule pas @ 100km/h mais le dépannage a peut de frais vous connaissez dans votre pays
exactly
Please adjust the speed govenor to no more than 3mph! Crazy repair of a super critical component. Looks good though!
Получилось красиво.
Все в размер, сотка в сотку.
Цапфа отливается и остывает в форме, затем ее обрабатывают. Это монолит.
И если этот монолит сломался, то восстановленная сваркой цапфа не внушает никакого доверия. В самом нагруженном на излом месте появились внутренние напряжения, а возможно и пузыри.
Не надо забывать и про то, что там, в Пакистане и Индии транспорт работает с перегрузом... Это традиция такая, пошло это с вьючных ишаков...
А зато... как Точно и плотно посажен переходник❤, никакой излом нипочём... МАналит❤❤❤
Всем Всех Благ, Аллах Акбар ❤
Метод в принципе рабочий. Единственное, штифт надо садить под прессом с натягом и наплавку делать на автомате под флюсом, затем делать отпуск чтобы снять напряжение в месте наплавки, и потом уже обрабатывать на токарном станке.
@@werke3268 с этим согласен.
Но ничего этого мы не увидели. Подгон в размер, а сварка не та. И никакой термообработки: отпуска в печке, повторной закалки.
На от@@бись.
чувак, там на станке дополнительной продольный суппорт отсутствует, какие еще познания в отпуске, автомате и флюсе?
@@werke3268 метод рабочий, говорите? Это только в том случае, когда деталь разрушилась вследствие некоего форс-мажора - единомоментного превышения расчетных нагрузок. Но у них дикие перегрузы - норма! И уж если оборвало заводскую ось, то никакие ремонты не помогут.
Там еще и резьбы под гайку не очень много осталось.
Мыши плакали,но продолжали крызти кактус .
If the original forged part broke there is no way a hacked up repair like this going to , especially the way they overload their vehicles..
The way you have written this means that the repair is going to last and not break.
it's not a hacked repair... it's a textbook open root weld with a post and then machined. Welders do this every day worldwide. Alaskan pipeline was joined/repaired the same way. Overloading is not the responsibility of the machinist
Yet it's done all the time and lasts. They wouldn't keep doing it if it didn't last. The welded area is probably stronger than original if they used the right rods.
@@LexusGX460-OFF-ROAD Western "mechanics" get bent out of shape if it's not always new parts going in. Repair has become sacrilege to most. It's rather odd considering we used to do it too before everything became unservicable junk.
@@okgroomer1966 sad part is,that it is probably better than some of the new parts coming in from China.....lol
For material experts ; its not question about if this part conforms to OEM specification or not. Parts are expensive and the lead time maybe very extensive means loss of business. The idea is to get the truck back on the road earing money 💰. The skills demonstrated are commendable
Looks cool and would make a great wall hanger for ''see what I can fix'' but no way this thing lasts more then a few bumps in the road.
If their repairs only lasted until after a few bumps in the road, do you think they would still be in businenss?
Привет ребята, здорово получилось, но по моему сварка на излом плохо держит!!!!
ладно сварка на излом , а снимать замеры микрометром на горячую это мега правильно , особенно под подшипник

This is some of the best induatrial comedy I've seen in a while.
Very nice. It should last a few weeks, then they can do it all again, and again, and again.
I sure wouldn't use a "repaired " spindle on any of my trucks .
Es que tu eres muy listo
YOU WOULD
If you had family to feed.
No social net to fall on.
And no money for the new part.
Oh you would....
@@w.loczykij5354at that rate one won’t have a family for long. Why was it made in one part in the first place and what about all the heat stress
These guys do repairs on items that practically never fail in western countries. Why do they fail in Pakistan? Three reasons:
# Terrible roads with pot holes that overstress suspensions;
# They overload their trucks;
# the parts were locally made from melted scrap metal of unspecified properties.
So, in that context, frequent breakdowns and accidents is what they think is normal and has to be endured.
Welcome to the real world for most people. A place of actual mechanics and not just part changers. Send the guy a new spindle if you're so concerned. I'm sure they would love to have it.
Puedes hacer una variante. Perfora la charnela hasta tener un diametro similar a la punta que se quebro Inserta un trozo de acero 4140 a prensa con la charnela en caliente y lo sueldas por atras con 7018 Luego una vez fria procedes en el torno a elaborar la punta de eje Esa es la forma que a mi me ha dado mejor resultado
Curious as to how you're grounding the part when welding, I hope you're not running the current through the lathe.
Of course they are!
What else would a precision machine shop do? Use an eyecrometer in a three jaw chuck?
you ground the lathe... it's an industrial lathe, not a wedding-dress
The lathe sits in the dirt if you didn't notice. The current probably has no problem passing into the ground without burning up the lathe.
@@LexusGX460-OFF-ROADif you work at my shop and you weld in one of my lathes without a proper grounding harness, I will kick your ass into oblivion. And so will every shop owner.
Incredible machine work but i wouldn't trust it after. If a forged casting broke how good do you think a repair would be after? This part can cause death with a wheel falling off
Судя по виду и качеству работ, эти трудяги ни когда не останутся без работы, это с однойстороны а с другой, они умеют, они хотят, им надо и они работают и ни кого не ждут и не ноют что всё плохо а берут и делают а главное делают всё, это достойно уважения
Si señor.....lo peor que se puede hacer......es No hacer nada......
Y punto!
Плохо только , что они себя не уважают.
@@Алексеймеханик-о2кможет быть ненашто

Поршня, коленвалы вытачивают сами. О каких технологических тонкостях тут можно говорить?! О каком качестве? Какие микрометры может выдержать станок, которому больше лет чем Ленину?
This would probably snap right off after about 20 feet down the road. This is a drop forged and machined part that has the grain structure aligned during the forging process, It has lost all of its integrity by being snapped and welded.
Eu já fiz esse tipo de serviço,só que no meu caso eu fiz outro eixo por completo furei a manga de eixo até atravessar e solda por trás.
E o que eu faria seguindo este princípio !👏👏👏👏
Esa es la MEJOR manera Asi lo hago yo y es la manera que aguanta
it's a technique that is just good enough to repair a donkey cart, you don't replace a part that is originally a forged part with welding in addition to arc welding with all the inclusions. It's simply dangerous I pity the driver of the truck no wonder there are many who leave their skin there.
Well in the real world you're just wrong. This is how every truck is worked on over there and they miraculously work when they're done.
this is surely why there are a lot of deaths on your roads and one wonders why the engineers designed such parts if it was not for safety. I am a mechanic and I would never dare to do a job like this and risk the lives of the drivers. I can see what difficulties they find themselves in on the road. They have all my esteem and I say bravo to them.@@okgroomer1966
Death trap what a waste of time
This is never being fitted to a truck again!! They're just happy you're all talking about it and sharing it, earning them an estimated $1,300 so far!!
Seems as good of a repair as can be expected. I feel bad for the guy who has to get the nut on at the end. Them threads are roached🤣
We used to do this kind of work back in the day. Now we can't get grown men to work.
Good work Brother. Teach the men to be men
life is cheap, parts are expensive ?
Better a truck wreck than a truck bomb.
Видимо, поворотный кулак стоит дороже грузовика, груза, жизни водителя и тех кого убьёт этим грузовиком, когда ПЕРЕДНЕЕ колесо оторвёт. Те кто пишет, что нормуль всё будет ничего не понимают в машинах и металлообработке. Кулак это ответственная деталь, потому, она кованная, из качественной стали, с термообработкой и контролем на предмет трещин. А это поделие запросто лопнет и гроб видимо сильно дешевле кулака. На ТО авто не допускается сварка рулевых тяг . Тут кулак передний, одноразовые люди.
во-во... Тут дичи какой-то понаписали - такие вещи, вообще запрещено сваривать.
Да нормально всё-пакистанские бабы еще нарожают😂
Wait, did he weld on the mill with the ground going through the bearings of the mill?
RIP bearings.
Такую деталь можно только выточить целиком и только из этого же металла. Иначе никак.
How many life you sucrifice..for this kind of job..life is precious..accident never happen w/o cause...
Кудесники. Сколько км до следующего ремонта?
Good enough to get the Bill of Sale signed and driven off the lot!
Цапфа не ремонтируется, опасно для жизни.
Bla bla bla
Хоть один вменяемый.
Waste not, want not, if it was re-heated and allowed to cool gradually, you might get a lot of use out of that part. Top marks for ingenuity!
You should be able to do a repair that will work on that. Mount it up on the lathe and pour out the center where that spindle goes but don't go all the way to the edge of that disc like part. Just bore out the diameter of the spindle. Now get a good piece of metal that's already heat treated and turn it down. Good carbide tool should cut it, but If it's too difficult, you could use a tool post grinder. Make a step in the shaft about 1/32" over the hole diameter. Maybe 1/64":(hard to tell without actually holding the part in my hand). Then make a second step about a half inch past the thickness of the knuckle. Champfer that edge. The temp difference is about 400F. You could probably heat the one part and avoid the dry ice if you had to. You can make up some by heating more, but you can start getting close to the temperatures that anbeal thf metal if your not careful, depending on your alloy. The expansion coeficient should he around 0.0000065/F. So multiply your hole diameter by that, and then multiply by your temperature difference. (Dry ice is around -100F) So a 2" shaft at a 400 degree difference should get you about 0.0052". So make it about 3-4 thousandths over. It should drop right in. The lock in place and never come out. shaft. Then turn the spindle profile down on the front side and cut the shaft off the back side.
You could probanly get away with making the shaft a bit smaller and pressing it in. If yoyr a bit nervous about it just being pressed in, before you cut it you could cut oyt the center of tge back side to a quarter inch above the surface, and then peen over the edge so that there would be somthing holding the spindle on if sonething goes catastriphiclu wrong like the knuckle cracks.
Would i fix that? Probably not unless I had no other choice. But it could be dove in a way that should hold.
I'd liked to have seen how they removed the round metal bar that they welded on at 10:53.
What could possibly go wrong but they would likely give you another if it broke, and you lived through the crash!
What they ran out of super glue??
JB Weld repairs everything. For a while.
fantastic art work ...bravo...
Nice craftsmanship. Lost art here regardless.
No one seams to have noticed that the spindle they are repairing has what looks like 2 previouse repairs .
That is the best job that was done on this site very well prepared and welded thumbs up
Snap, crackle, pop and she's broke again!
Of course NOT"Amazing Technology1" likes it.
Have to wonder how many UA-cam channels he has..............
Vernier… “very near”?…… for precise press fits? Spindles usually bend instead of breaking at that point. How did it break?.. wreck? Not sure I’d trust it. Broken spindle would give you a wild ride
I'd bet way overweight and horrible "roads". You'd be amazed where these trucks go. Repair is the only realistic option.

Многие пишут про термаобработку и прочие заводские нюансы, учитывая что это передняя ось и нагрузка на неё не большая относительно задних осей, так что ещё 100 лет проходит потому что сварка правельная и электроды высокого качества, сам занимаюсь производством и точно знаю что говорю , а эти ребята знают не хуже нашего что и как делать , так что молодцы!!!

@@emilioernandez9907 по нормам .на заднюю ось нагрузка 10-12 т,т.е 5-6 т на спарку . Причем и размер подшипников и длина ост сзади больше. А у передней оси нагрузка до 8.5 т.. т.е 4.,3 т на одно колесо.. Так что где больше нагрузка на ось..большой вопрос. Два...оси сваривать нельзя. Этому учат сразу..я уж забыл когда мне это преподавали. Если уж ось ремонтировать, то только через втулки с нулевой посадкой,а сварка только для финишной фиксации. В данном случае ..надо было выточить новую ось и установить с тело кулака и обварить в теле.

This truck was most likely overloaded from the start, I'm sure they will overload it again. In the long run, they would have saved money to just replace the part. When it breaks again and I mean soon the truck will be out of service and not making money.
They make these repairs all the time. You're correct they'll overload it and the bad roads will break it again. You are wrong if you think it's much weaker than original. If you ever travel to the 3rd world you'll be amazed at the vehicles they keep on the road. Almost everything is repaired out of necessity.
Очень рисковый вариант ремонта
Bravo les gars,vous êtes des champions ! Super travail . Du veritable artisanat .💪👏
Yeah, it's a bodge repair, but might last a while. Who knows. When you haven't got any money or you can't get the part you need, you do what you can.

Great effort with rudimentary tools, might work for something that does not require precision, however “any port in a storm”
The original one was broken to two pieces by torque, the newly added core stick maybe too thin.
I think that was just to align the two pieces, not for strength.
Not too sure Kurtis would approve. If the filler rod was the right material, the repair could work.
It's look like new. Very impressive work.
not a repiar that I would want on my truck 🚚 🚚
When Kurtis does a weld repair on a high stress part he doesn’t do it with a60 year old welder and rods of unknown quality, he uses flux wire with argon shielding a bit at a time on a turntable, not on a dirt floor without a really good preparation first.
At least Kurtis would leave us with an impeccable video including outtakes!
@dusterowner9978 it's a 6013 rod, stronger than the base material
That wasn't broken, that was intentionally cut. That part should never be repaired, it should be REPLACED.

All the comntators there is one very important point you're not seeing or thinking about. Offcourse it will break when ever it is over loaded. This repair will buy him time till he make some money. It is a good idea.
Не надо перегружать машину и не придется чинить. Ладно чинить. Других участников дорожного движения рискуют втянуть в дтп.
I might use that technique to fix a lawnmower wheel. Never to fix a medium duty truck spindle. They are crazy.
Why not if the welder is competent? Weld is incredibly strong. Only reason western countries don't do this is labor costs, not the effectiveness of the work. We used to do it long ago.
Why was the surface blue after the first round of lathing? (After welding)
Because it's still hotter than Hades after the welding! lol
Great work bro but spindle welding only 7018 with tuprature not 6013 china rod❤❤❤❤❤❤❤❤❤❤❤❤❤❤❤❤❤
Agora é que vai quebrar bonito
You guys are amazing masters at your craft 😊👍
Hebat cara nyambung besinya.
Skills enough, but how strong would it really be?
The axle-stub shows dropforging marks, so 800-1000 Mpa (?) if alloy steel was used. The welding, 400-500 Mpa? The residual stress caused by the welding due weld crimp ?
I estimate 30-50% less strong. Some (expensive) weld-materials can be tough however.
It will do some time again....

This is where you really want to think about liability. If you were to be faced with the lawsuit, the plaintiff is going to ask by what authority you have to repair a spindle back to OEM specifications and that machine shop would have to prove their case. Sometimes you need to just buy a new part. Besides, I don't know where this got repaired, but here in the states I would think it would be a fortune!
Lol this is Pakistan not no bitch ass western country with Emma and her two moms. No such thing as lawsuits and shit there. They do what gets the job done. And they did a great job

Is this a common failure? You would think the axle, having to experience the higher moment, would fail first. I guess if you’re reusing the spindle after axle replacement the spindle would eventually snap.

Yea, i definetly have to agree that the metal will have anealed in heat affected zone. Its possible that. Proper selection of filler would allow the part to be heat trreated again after the repair but i dodnt see any indication that was done.
