These OSHA workplace safety videos are really great!
😂😂😂😂😂😂
You need to preheat prior to welding 4140. If not the weld will be very hard and brittle. You can't treat it like mild steel LOL!
I wish TH-cam would stop recommending people from 3rd world countries who i wouldn't trust to fix my lawnmower.
The center pinning is far preferable to the weld weld weld weld stacking some others do and keeping in mind that sometimes new parts just arent anywhere to be had, there are times when all you can do is fix things as well as ya can with what tools and raw materials ya have access to.
It would be nice to see a longevity/test video to see just how well this type of repair works and what loads it will endure.
Taking into the consideration the tools at hand for the lathe operator it's a very good work. Providing the driver of the vehicle operates in the correct manner it will hold. Keep up the good work. 👍👍
I can really appreciate this. Working with what you got. Genius.
You should welded doing stronger passes with 8018 welding rod for this type of base metas like an axle of a truck.Preheat the axle to about 250 farenheit before welding.
I would agree. The welding process is the weakest link. Axle won't hold up under stress for very long
I never knew there was so many pro welders until I read the comments. It's amazing what you can do from your mother's basement ...
It's a while world of people, and most of them know more about welding. There's more to welding than sticking metal together.
@@mezmerizer0266 Agreed. Some have forgotten that schools use to have shop classes that taught these skills. Plus some professions one has to learn the skills or lose lots of money and time.
Haaaaaaaaaa
Wow !! This shop is first rate. Brick-paved outside, not just dirt.
That's why this guys never run out of work 😂😂
I see on near the original break some discoloration that appears to be heat, and perhaps signs of a previous repair. Had this axle been repaired before in the same spot?
That's why they never run out of work 😂😂😂
It needs to come back for the next guy so he can make some money too 😂😂
There are lots of criticisms about this repair. But if you consider the fact that the truck is down, and the fact that getting the truck back up and running as opposed to sitting and waiting for a new axle to come, which might be days or even weeks, this fix might be a very worthwhile. If you've ever waited for parts that sometimes take forever and heard that familiar phrase "backordered" then what is there to loose? You can critisize the technique and the wonder about the strength but meanwhile that truck is out making money. And who knows, it might just be practically as good as new? Very nice job!
What's the torque strength of welding rod?Maybe a grade 10 threaded bolt threaded on both sides then weld..Either way its a temp fix I bet you get a month tops..But it was fun to watch..I enjoyed it.thank you.
Its gonna break right next to the cracked repair
No problem. It only has to last long enough fot the current owner sell the equipment.
@@jamesmason2228 า
It will get u buy for awhile but I’d be shopping for axle
Świetnie się to wykonane i bardzo elegancko jest to pospawane pozdrawiam twórcę tego filmiku 👍👍👍👍
Ya that's some quality work .
Only one possible improvement really (other than making repair larger than original diameter then turning it down): tight sleeve the repair 50% longer than either side and weld that sleeve at both ends thereby adding additional torque capacity and strength to the repair.
That may not have been possible though if it posed interference to other parts.
Possibly although a lot of older vehicles have lots of space to work with.
Yes .. exactly right … it will be out of balance but ok for low speed …
This idea shown ok for jury rig but not for road !!!
@@ChasOnErie
Why would it be out of balance? A sleeve would be adding material equally all around the shaft. He could also turn it when completed to ensure the thickness is equal.
I had an axle repaired in a similar manner ro this by a qualified engineer on a sporty GM product.The axle too was pinned, preheated and welded with the most suitable rods. It lasted just over a week!! Broke next to the weld.
What the engineer did was to get the vehicle moving and it did. No axles were available. Luckily a week later one was but had to be redrilled to fit the car. Same raw part but finished differently
Both of us wondered why it broke in the centre,, it is metal fatigue pure and simple. This 50 years ago.
Never seen a centering drill before on these channels good improvement 👏
That won’t fail. Ever.
I’v been taught to look away from the welding arc so much, I looked away when he started welding....
20 yrs in ship building I never got a flash, I took heed and turn away from an arc,
I wear my auto tint shield. Safety first.
Neat little repair job. I liked that the guy didn't do it the fast rough way, instead using a centre pin to keep both ends perfectly aligned. More work, but later more satisfying results.
Except that between the pin and the undercut, there’s about half as much axle material to transmit torque. And if the axle flange is not perfectly aligned, it will flex at the weld and break very quickly. With gentle treatment it’ll get by for a short while.
@@billmiller7138 Yep, you're right. I also noticed that. I'd have bevelled both sides of the joint down to the pin before welding.
And yeah, both ends won't be perfectly aligned regardless how much the guy tries.
Far better, but more expensive, would have been to take a new shaft and weld the flange onto that. Only then you have to find a way to align the flange. Sigh...
But I suppose it's still better than no repair at all.
I repaired a 20 ton forklift Axel four years ago similar methods. Press fit 5-8" press fit center pin. Dial indicated, pre heated 400 F , 110-18 all stringer beads, maintaining 400 F . Hung it vertical in a barrel full of hot ashes to cool over night. .002 out of round . Left the weld area larger than shaft 0.D. still using the forklift.
@@williepelzer384 It must be very satisfying knowing that your work keeps someone's machine running. I don't have that as a design engineer.
@@mikethespike7579
A new shaft? The point of the video was that new parts were not available. Apparently, cost was not the issue.
Not to mention, this work was done for a mere $1.47.
Nice approach. I hope it works. My only concern is the strength of the welding rod vs the shaft steel. That’s a lot of torque. I don’t know if the material will hold up. A for effort though!
Looks like a torsional failure at timestamp .02.
Not really an issue of load. The original shaft was most likely made of inferior grade steel. As such, it looks like it was cavitated and broke from a drop (pothole or rut most likely). The quick fix will probably (most likely) last longer than the vehicle. As for the welding rods themselves, they are most likely mild steel which is not as likely to work harden. All in all, I wouldn't race that axle, but it will last long enough and be strong enough.
I've been a welder for many years pipe fitter structural steel ship fitter and I'm telling you people the stress that's put on that shaft that Weld will not hold it might work for a couple of weeks they could get lucky a few months and it gets to work done makes some money and buy a new one But that is definitely it's not gonna hold that's a temporary fix
Maybe back down the hill. That’s it.
Why mark the shortest piece with white chalk in two places especially when you never worked close to the hub end?
I couldn't see where the earth clamp from the welder were placed but if the current is flowing via the bearings, to the chuck jaws, to the part, you can end up destroying the bearings.
I think the two chalk patches on the hub end are where he “scratch” indicated the piece to be concentric and parallel… and it appears to have worked.🎉👍🏼
@@russberry3240 Ah, yes, good point, I think that you are right, silly me, that would be an obvious thing to do.
The problem with all these india repairs is they don't seem to understand heat treating.
Soviet engineers were bad teachers (because many of them are good mathematicians and poor mechanics!~)
Great job brother. All good wishes from Bengaluru. This restoration will keep the truck (looking at the length of the axle and besides there are hardly any rear wheel drive cars anyway) going probably another 50,000KM provided the driver is careful not to overload his truck.
careful not to overload his truck
HAHAHAHAHAHAHAHAHAHAHAHAHAHA!!!!!!!!!
The black stuff will hide the weld defects if you did not know better the repair idea and location could get you thru for a time.
As an Engineer and Metallurgist I would only do this if I was desperate
He probably was since this is a 3rd world country. Kind of like Cuba with there 50's cars the patch them together and keep rolling.
As an engineer, hahahahaha , no one cares for your degree, clearly you continue to sit behind a computer and ponder. This guys is coming from experience,
In a desperate situation, I'd choose my brother from the video....
very nice job, it will last for one more week...
Vocês são excelentes profissionais
If this guy had a good lathe he'd be dangerous,,, great job .
Usually I watch and praise your hard work. This time i call Bullsh%^. Been ther done that NO, NO NO!
You CANNOT weld a drive axle and have it last the way you did. NO!
You needed to turn and sleeve, then Tig in an inert atmosphere. That will break, 1st good flex!
Nice work
good effort!
THANKIOU
I think that should have been heated before he did the weld. It will be brittle I am sure.
Great job 👌👌👌👍👍👌👍
Waow mantap cara menyambung as nya hadir nyimak video nya sahabat 🙏
What country is this? They are very resourceful people.
Oh holy crap, COVER THOSE WAYS if you MUST weld with the part in the lathe, but preferably don't. And then you throw grinder dust on them 😞
Who needs cutting fluid or a non wobbly lathe ?
Now make a mold and cast a new one, if possible.
Show parabéns
I’ve got shortened axles in one of my race cars which were butted and have a collar. Never failed in 40 years. An axle without “C” clips can easily 1/8 to 1/4” shorter and work fine.
Not bad, for having minimal options.
Take that national Backorder, this is how it's done
It's a get home fix, however quite
Well done. Baby it home, go slow
And be gently on the gas. Watch
Out for pot holes..
The welded area has to be stress-relieved for a number of hours. If not, it will break at the weld.
Trinidad & Tobago.
West Indies.
For the truck, we have to find a new owner.
Carefull driving, it will keep for years.
Craigslist ad coming soon...."low mileage heavy duty truck for sale, garaged, all maintenance kept up to date, one owner, used only locally by an older gentleman, no issues. Firm on price I know what I have". 😂
He is not a mechanic, he is a fitter and turner.
I hope that's an axle from a horse cart. Is that 4140 steel?
I wouldn't trust that to go around the block
Everyone assumes that the repair is finished at this point. I'm assuming there will now be a trip down the road for heat treatment..
Great Job
Been there, that will snap likely next to the weld
good work how long will the axle last 👍🙏
Until it breaks I'm thinking quite awhile.
imagine if they have good machine,they do wonders
Great work. I was actually thinking today that there is talent sprinkled even in places one might not expect. Look within and with diligence find your own...I'm still looking.
Reminds me of pipe fitting at Camanche Peak Nuclear power plant.
Damn.
I believe that's going to last until the first Hill
Maybe It Will break again, but if they do It there is a reason, and the reason is that It Will work.
What about Balance?
I think it will hold very good. Looks like a great repair job!
I dont think that would hold. The only way to do this is a pinned key or removing the entire shaft and welding the hub onto a new bar and cutting the splines. That's the only way it wont break.
Good job, but I believe it was not available at the market though.🤣
I predict maybe 20 minutes of driving time for that repair. LOL
Так эта полуось и сломалась в месте предыдущего ремонта.сколько уже раз говорилось "полуоси не варятся".это ремонт для того , чтобы чисто руки занять ,не более.
Should say. Available everwhere else in the world but not dirkdia.
When you gotta do what you gotta do?
Good job
That will never hold. Ever. The weld is infinitely softer than the axle.
All I could think about was how damn slow that lathe was running even when the video was fast forwarding most of the video!!
I can predict the future. I can tell you exactly where that axle is going to break next time.
Ha ha nice root pass btw.. dohhh
Although the repair will never be as strong as the original shaft, the repair could have been made stronger by using a smaller diameter dowel in the center. The strength of this type of repair comes only from the filler metal that is welded to the shaft. A smaller dowel would have allowed more welded filler to be added on.
I can't imagine this repair lasting very long, but it could get the truck to the closest repair shop that has a new axel, if it has no load and the driver shifts smoothly.
Good 🍁🌺🥀🥀🌹🌹🥀🌺🌺job
hello friends
Just going to break again
Can’t weld an axle? Hold my measuring tape bro.
I would have used a case hardened DOWEL with an interference fit in-between the shafts. Then after welding and warping heat the shaft to anneal it and get it straight again.
I was thinking like a 1/2 inch key but I agree- the concept is the same trying to increase the torque strength.
I rather use premium grade repair sleeve on reduced OD of the shaft halves; bending stress still may be the issue, but not the torsional stress.
Looks like 7024 rod
That's prolly 4130.. Brittle wield & no sleeve.. will last about a week..
No oil
Guarantee for 1 day or your 10 Rupees giving back to you
A.) I suppose driving around on an axle that is gonna break in 2 weeks is better than driving around on one that’s already broken, & B.) y’all need to learn the definition of “brilliantly”.
Lol it won’t hold for long the hardness if axle steal vs welding is way different
I've seen them do much better weld jobs over there on other videos.
Why does everyone say "it will break" when they have no clue what its fitted to! what a 25hp 1960s diesel truck.. prob last forever.
Absolutely AMAZEBALLS!!🤘🎸🤘🤩
Got a sub, like n comment from me!🍻🍻🤘🎸😎
I understand that when resources are limited you have to do what you have to do but……there’s no way that axel is able to perform the same function when reinstalled for any real length of time before it’s broken once again.
He could find a steel bar that diameter and just do it right. Replace the whole thing. Recut the splines.
Главное рулетку приложить
No matter what everyone says it's amazing that he does it with the limited tools available to him. All these machinist these days need carbide inserts just to turn it down, most wouldn't have a clue how to grind a piece of cemented carbide
It's called the progress of technology .
This "repair" will not last long, especially when they overload the truck and this thing just snaps apart. Axels are made from one piece of very hard steel that is heat treated to be strong. You can't just stick weld it together and think it will last.
This will never hold up to any large amount of torque. Perhaps the truck can just be limped home under low power until a new shaft can be found or made.
For a repair like this to work at all, the axle shaft would've needed to be heated up Very hot before being welded. Then after machining it, the shaft would need to be heat treated again.
Definately not an American machine shop...lol
Driver must dangerously overload vehicle to get job to make
money to repair vehicle after it breaks due to overloading.
Everyone is too busy making repairs, no time or money to build
good safe roads so everything breaks. That is their system.
It will NEVER hold up to any load. Anyone who has ever used a Ford 9 inch rear axle in a quick change rear axle knows that the set up uses two short axles and they have become hard to find. In a standard configuration there is a long and a short axle. I have seen many attempts to shorten the long axles as a cheap way to go and you get what you pay for. Most will never make it past the first heavy load.
A popular Spanish saying "Lo barato sale caro." Meaning the cheap becomes expensive...
Welding in your lathe? Any good machinist won't even grind in their lathe let alone weld.
lets cover it in black s##t then it wont look to bad.
Should have been preheated.
