Horrible hopefully the abrasive dirt protected the surface of the gear.. when they welded different metals such way that there ar large internal tensions in the material. Even with the same equipment this repair should and could be done way better. Amazing technique is correct, but not in a positive way.
Buen trabajo, no todos pudieron aprender con maestros torneros las medidas de seguridad, las técnicas de trabajo, los elementos que se necesitan. Hacen lo que pueden con lo que tienen, si se les daria un curso de torneria serian muy buenos torneros.
Yes it is a spiral compressor rotor, I used to help manufacture them and they are designed to run as a pair with one of them having four flutes and the other having five.
Компрессор хватанул жидкость. Какая эксплуатация = такой и ремонт. 20-30 годы прошлого века. И разбирают всегда в песке и пыли. Так наверняка крепче будет.
you dont... dont... dont.., are we condescending again? why are you watching this go and watch some football game instead. Let people be and go after your buisiness.
@@iroker Why are you so sensitive? You act like a child on any bit of criticism. What the poster has stated is 100% correct, You DON'T weld on a lathe, it is a known fact by machinists and you DON'T grind on a lathe either as the abrasives destroy the ways of the machine. Get some knowledge you Punjabi prat.
Where the current flows depends on the location of the ground. We can’t tell where the ground is but belongs next to the weld. That can be rigged well enough but they aren’t aware, I suppose.
@@iroker , I’ve offered to give advice on best practices but haven’t gotten any takers. These guys are making it up as they go. They do pretty good, considering.
Rotor de um compressor de refrigeração tipo parafuso. Esse compressor trabalha a 3500rpm acho que esse tipo de solda nesse eixo não é muito aconselhável
@@hydroman99 I'm so worried that people will just assume this is the way machining work is done. I'd be stomping on somebody's head if they did this to my parts.
@@hydroman99 I didn't' see anything about cast,,,Really didn;t see it. Tey would have had to use Ni Rod, which they didn't. (I have welded cast to mild many ties and written the procedures man more. My choice would have been J groves for a lot of reasons. Less weldmetal to induce stress and add heat input, but mainly to not have to weld so much. The bigest problem I saw was the weave beads instead of stringers. They DID induce a ton of uneven stress for sure. ....The biggest problem I saw though was why did it fail in the first place? looked like a very localized torque failure. These guys don't even have shoes but a radiograph would haven been my first move. One other thing. You ever notice in almost all of these Pakistan Vids. the lathe operator is always trapped between the lathe and a masonry wall. If anything goes really wrong that is where that are going to find him....He has no place to run to get out of the way. -
@@mathewmolk2089 The stub shaft they made was from a poured slug. The chips from the machining operation were dull grey and discontinuous. The chips from the gear shaft were blue continuous chips. Nickle rod is expensive even here in Canada, nevermind Pakistan. My guess is that they used 7018 or stainless rod. I agree the lathe set-ups make me scratch my head. Every shop I worked in, we arranged the lathe against the wall, saving room and making work area more versatile. I enjoy watching these guys just the same, it is like a machine shop in western world 75 years ago without any tables, chairs, work benches, etc. Nothing makes me cringe more than how they use their hand to slow the lathe chuck down. I guess those 3 seconds add up to 3 minutes/day and that is worth the risk of getting injured.
IF this is the same material that the original piece is out of then this is OK. IF NOT...then the metallurgy under full or almost full load will ultimately fail....again. DON T KNOW what they used to turn down the piece. LOOKED like MILL STOCK that would have a VERY specifc material schedule to go with it....BUT ....that is not in this video. Still....basically a reasonable technique and enjoyable to watch.

What happened at the end, did the end fall off with the tap of the chipping hammer?
A worm? More like a spiral compressor rotor.

demaciada soldadura podia aber revajado y meter uno dentro de otro y despues soldar

Ha roto por donde lo reparasteis la ultima vez y cuando lo hagáis de nuevo, en breve volverá a romper.
It will last a maximum of four weeks.
You don't weld on a lathe because the current goes through the ball bearings

Look at the runout in these machines, are you sure they have bearings.

This is so painful to watch. Have they not invented the workbench in that place yet?
Or how everything is tossed on the dirt floor. Welding cast iron to carbon steel seems to be an act of desparation.

@@hydroman99 In a nearby workshop, new hands are being made. Do not worry.
Nice 👌

no es el peor trabajo que e visto pero tampoco el mejor
No quiero saber cual fue el peor!!!
Кровь пошла из глаз
Без песка то оно, бля, и работать не будет!
good job
Nice work
I don't think this will last very long and anyway the accuracy will not be enough to work
Sao các bạn không nói lại sát mặt nhông mà nói ngay khớp nhỏ nó dễ bị gãy trở lại
Non terminate i vostri video!
I can't watch any more.
Why do they bother, if they snapped a good shaft how long is that terrible weak job going to last.

They must need it.
