8:33 микрометр? Не, не слышал. Варить на токарном станке? 😲💪На месте сварного шва надо было синей изоленты намотать, а то как-то не по ГОСТу получилось🤪17:43 болгаркой на станке🤯ты бы ещё включил станок, чтобы деталь вращалась, для увеличения "цилиндричности" 😁😁😁😁 Др.Дью упал бы в обморок если бы "это" всё увидел, а Матвеев бы забухал на месяц🤣🤣🤣🤣короче 250 полуляхов из 250🤣🤣🤣

А, работам на токарном в перчатках тебя не смутила?
@@OOO_Pro-Mold там всё меня смутило, мягко выражаясь
OMG! As a professional blacksmith and welder, it hurt my eyes to see what they did there.
9:33 You NEVER ever fasten your cutting tool with just one screw at the tool post!
Stick welding this thing whilst in the lathe...they don't even bother to protect it from the splatter.
The weld...well it's hardly worth commenting but one thing is sure welding on slag won't make this any better.
I don't know what he does there but welding looks different.
16:54 Oh yeah..now just some nice finish to make it look decent. "Grinder and paint make me the welder I ain't".
вот же народ какой басиком работают вообще и с металом и с огнём. Не нужно им высоких технологий так всё делают на глаз. Какой то КЛУБ ВЕСЁЛЫХ И НАХОДЧИВЫХ одним словом. Молодцы.

terrible welding as usual. But good to see that child labor is still thriving!
If it was a seized bearing that caused the shaft to snap then a good repair may last but this wasn’t a good repair. The new shaft was cast from who knows what grade of steel and the welding was poor. Welding over slag is a big no no, it causes porosity. If you’re going to weld it while mounted in the lathe then taking a cut after the slag is removed will give an even, flat surface to weld on and reduces the chance of inclusions and holes.
Good to see the guy doing the casting wearing his PPE “Sport” flip flops so that if he pours molten metal on his feet he can run like hell to the river cool them down.😂😂😂
Love the dedication, and effort put into repairs like this. But doubt that it lasts, if it even works. Some things just can not be done in a backyard fashion. When this blows up it will likely destroy the entire machine they were trying to repair. Some education in metallurgy, and proper welding techniques would benefit these fabricators so much. Interesting video to say the least.
Indeed. I was wondering if they have the capacity to work types of steel ideal for this application. I suppose high ductility would be most important. Then I saw they built up that huge piece with welding rod and I thought ‘that’s not right!’.
Though I agree with you I would love to know how long the repaired cutter works and how it fails. Maybe they will surprise us!
A part like that is super expensive. If they bought it broken basically as scrap they may come out ahead. Of course, if it fails catastrophically it could damage equipment and maim or kill.
But no need to worry about the latter as they are clearly very safety conscious!
My snideness aside, I do admire them for effecting this repair. I would love to see a similar repair done in the US, Germany, Japan, etc. i assume the process would be to order in a part from the manufacturer that was already machined and heat treated.
i agree, the size of the gear itself should tell you this thing is under some serious load. for some reason in Pakistan they think highly of their welding skills and methods. i bet if they had cameras on the road we would see some serious crashes. i wouldn't trust it for nothing.
@@DennisHicks78749 111
@@DennisHicks78749 gentlemens, did you not realize that this is not the first repair? Before that, this part had already been welded, an overhead clip was made, it is possible that the trunnion is already not native, but replaced. Externally, judging by the nature of the fracture, it looks more like this trunnion has already been welded in this way. I am interested in another question... What did they weld? Here's what was obtained from the melting furnace - it's either cast iron, or it's unclear what. And how it was welded at all is a mystery.
By itself, this is quite a working method, so I restored the gear shafts, the shafts of electric motors, and they work to this day. And I welded by electrode welding, why TIG in this case? These shafts work to this day, everything is fine. But the welded steel was intended for welding, and not for the incomprehensible composition of the metal from the furnace...
Agree... I praise their dedication and effort, but this is not the way to do this. For starters, why is everything in Pakistan dropped/worked in the dirt?! You have what looks like a 5-6 start helical gear that's ground and some degree of polish and they keep dumping in the dirt on the floor of the shop. Then they lift it with chains on bearing surfaces and the chains rub up against the gear teeth...
The lathe looks like it's on it's last legs... Probably sold off as scrap from Europe or the UK. Chuck is not great. Live center is pretty crap too.
Then there's that shit casting of mystery metal and the porous welds that guy was laying down, not to mention no means to keep spatter from adhering to the running surface of bearings or the gear teeth. This repair is doomed. I hope no one gets hurt when this thing lets loose...
I see lots of these videos. There are clearly experts from well equipped countries shops in developed countries suggesting this will fail - I suspect they are all right. Probably if these were built from the correct steels and hardened shafts with a thorough maintenance schedule they may never have failed in the first place. In terms of what these guys achieve with basic equipment and what they have on hand I'm blown away by the results they get. I would love to know how long these repairs last
I suspect its a compressor vane from a screw type compressor. The tolerances are super tight on such things, it needs to rotate with a matching partner to seal air and the tolerances these guys are operating with arnt even in the same planet as whats required. This part will never be assembled, it simply wouldnt rotate against its partner. And if they assembled it loosly enough to actually be able to rotate, the repaired part will not be balanced, so itll never spin at the required speeds to compress air. And even if it did spin, the join theyve completed here is terribly weak. The metal theyve welded to the end is the wrong type, its not chipping like a high tensile steel, more like cast iron to me. It will fail, in seconds, if its spun up to its designed operating speed.
Id be elsewhere for such an event.
But I stand by my first point, this thing is never being assembled ever again. We're seeing a pantomime of metalwork. All this part is good for is generating hundreds of positive comments from people who have no idea what theyre watching take place, and hundreds of negative comments from metalworkers who know what a shitshow this is.
@@shutupmeg176 Yes, that's right - one part of a screw pair on a screw compressor. And yes - it won't even last ten seconds! In such clips, THEY NEVER SHOW THE REPAIRED PART FITTING INTO THE MACHINE AND THE MACHINE WORKING!
app. 2-3 months
*I'm not sure what amazes me the most. The fact this popped in my recommendations for no appearent reason or the fact I watched it till the end. Fascinating.*
Work fascinates me. I can sit and watch other people work all day.
Looking at the chips, seems like the mad max furnace was pouring cast iron... so this entire work is dedicated to a massive blow up !
Очевидно что этот вал уже ремонтировался и его оборвало снова, нельзя просто так взять переплавить чермет отлить кусок вала и приварить его , это место высоконагружено и из за разности составов металлов его будет обрывать снова и снова.
ротор от винтового компрессора! стоит охуенных денег
بہت خوب ہے ماشاء اللہ
Will someone please buy some goggles for these men?
Amazing yes, but it appears as if they are welding slag into the weld. Or welding metal over slag.

Как же точно они измеряют. Рулетка диаметр отверстия и вала. Просто супер. Зачем люди придумали штангельциркуль?

Respect the micrometer and do not forget about the caliper, remember about the ruler. But know that only the right " by eye" is always with you!😁

@@igorsh5611 а что такого прям криминального в подшлифовке, ну кроме абразива? Конечно, не укрыть направы при этом - это преступление, но сама по себе операция вполне рабочая.
اللة ينور بس في ملاحظة الي فرغ الدرفيل بسلك دة اكبر غلط حيادي الي تازيز في معدن الزهر بعد ما كب على المخرطة استعمل السروخ
I'm a Plumber by trade these days after spending 30 years in the hospitality industry. I'm no machinist but I can think of at least two instruments specifically designed to measure the diameter of a shaft and a tape measure ain't one of them.
I didn't like that weld one bit;
The end of each pass should melt well into the 2 parts at the ends, at the beginning and end of each pass, not just over the previous weld in the middle.
I don't think any real planning went into the repair. The shaft looks to be a separate piece from the rotor/screw, so while it may not be feasible to press it out in its entirety, at least you could fabricate a new section rather than trying to hold the thing together with some chewing gum and a snickers bar. If its in some form of compressor service, both the runout and the load capability will be quite critical. Here the shaft is now just some random metal they had lying around and a bunch of welding boogers. I wonder if it even worked at all?
Nice bro
o eixo original e aço carbono e eles fizeram ponta de ferro fundido

Dudes doing their best with the tools they gave. Respect. Why can’t the owner give them some tables to work on instead of the filthy floor?
I don't agree with that I don't think they did their best. They had a kiln right outside. Once they center that if they sent her that and put their first tack in the center they could have easily built a pour box around that big gap and fill the Gap with continuous steel. This is what you call a hack job when they're just trying to get paid for throwing it back back together. Personally I would have just bored into the existing shaft poured my new shaft. Threaded the existing shaft threaded my new shaft twist together cut a v and welded a small v then turned it all to fit. At least that's what I would have done with the tools they had.
Система тяп ляп и так пойдёт. ресурс у них просто аховый день два и опять в ремонт )))
Гарантийный ремонт .сломалось по месту ремонта )
If the hardened steel shaft had issues, I can't see something made by random steel casting and welding standing up in the long term. There is a right way to do this, but unfortunately this is not it. At a minimum I'd at least like to use some bar stock made of a similar alloy and treatment to what is being repaired.
Yes that was my question as well why they didn't use the similar steel !
Casting shaft and welding to different steel ??
I'm amazed they do not use JB Weld or Super Glue. That is what is amazing.
They probably would if JB Weld was available!

Very good video.
It said high speed drill on title.
I was curious as to what they would drill with that type of drill.
It doesn't like any regular oilfield or water well bit.
Thaka again:)
That is not a drill, it is a rotor from a screw compressor.
@@316tomiller Interesting. Gonna have to google that.
Good job👍👏
Conventional friction welding can help here. A simple operation to repair broken shafts.
Boy, THAT IS a bunch of HALF-ASSED work
We never get to see how long, if at all, some of these hacks hold up.
Good technical
Do any of the men receive shop training out side of the machine shop?
Amazing what can be done with no steady rest, a wobbling tailstock, centering by eye and not with a dial indicator, stick welder instead of TIG. I too am curious to see the follow up video on installation and the machine running with the repaired rotor.
I think a lot of people would like to see follow up video's of the destruction caused by 'repairs' of this type.
I don't think there has ever been a follow up video of anything though and probably never will be. I think the video's are trying to show how 'ingenious' the people are not how well they screw up?
Safety first!!!
Whoah!, that hurts! No problem with ingenuity but will it be durable? I would rather use the induction heating for joining 2 undefined steel... and of course safety first!
🔥🔥🔥🔥🔥
ребята индусы одно прошу если вдруг Россия будет у вас это закупать не продавайте им скажите что вы ввели санкции ,ведь жалко людей да и напрасный ваш труд
По моему там можно было расточить центр и как нормальные люди впрессовать новый кусок вала. Родной вал вроде впрессован, а не монолит
It look like somebody handed a baby a computer and said fix this please.
Ротор от винтового компрессора, скорее всего от 40 м3.
I love how health and safety is never compromised on in these shops.......plus there are way too many Jawas working there........
🤩👍👍👍👍👍😍
At work I do not use lon3ta to center or compare, I use 7018 welding which is hard and should have been finished with a stone grinder
as a machinist all I can say is yet another "great how not to do..." video
Just imagine if they had cast an actual round, symmetrical cylinder to begin with, they would have had nothing to film.
Why they didn't use normal steel ,why they cast the for a shaft ??
Anybody knows??
Anyway it was unbelievable 👍🌺
И они думают что такая шляпа долго проработает? Наивные. Пукнет при первой же серьёзной нагрузке.
Нагрузки на этой детали не будет, т.к. это ротор винтового компрессора, а не червяк редуктора (как написано в описании). Оборотов порядка 3000 в паре с таким же ротором, в чугунном герметичном корпусе с маслом. Скорее всего этот хвостовик из сырой стали согнётся, роторы заклинят друг с другом и угробят рабочие поверхности обоих роторов.
While I appreciate these fellas' ingenuity and hard work, this is so wrong in thousand ways. Combining an improved and heat-treated steel with a random mixture of "some" steel, is a recipe for disaster.
This rebuilding process is invented by Disney and is called Mickey mouse repair. The build-up welding on the lath at about 13:28 really scares me. There will be numerous holes and voids in the welding. There is no way the shaft would be anywhere close to the strength of the original.
This proves you don't need safety glasses when grinding. They must have a eye doc on call...
the eye doc shows up with a garden hose and sprays their eyeballs. all better!
the shaft wasn't centered in the lathe and the weld is full of voids....it would be interesting to know if the unit functioned in the machine and how long it survived.
I seriously doubt it. To add insult to injury to the person who is at the mercy of these "machinists", the shaft looks to be pressed into the rotor in some fashion, so there was probably a way to properly fabricate a new section out of something other than just random metal and weld splatter. Others have pointed out that its likely a screw compressor, and those have fairly tight tolerances to work properly from my experience with working on a supercharger I was trying to rebuild. I decided to abandon it and get a replacement as it was too far out of spec, and that would be ultra-high precision compared to this. The repair is comically awful in a really tragic way.
@@mysock351C I worked on Ingersol Rand compressors without the special tools but had the materials to make things 35+ years ago. That would have to be a seriously large machine as the 175SCFM rotor was tiny by comparison.(175 SCFM through four 1" bore lines)
The 175 needed at least 80 hp motor to drive it but 100hp Deutz diesel was fitted so max output could be used. The biggest compressor 'we' had for hire was 600 SCFM but no one ever got into that thing in the 8 years I worked there as it never got used to full capacity

EEEK. You had to reweld flux holes, theyre going to be all throughout the metal. This is not a job for stick. Those weaknesses might bring return business though?
quite correct-the porosity will harm the effort.

Потому что не знают что он существует. Все намного легче починит, если не понимаеш что ты делаеш. Если понимаеш тогда ремонт намного сложнее получается - примерно что когда тебе нужен кусок хорошая сталь, значит надо купит такой кусок, а они просто отлили болванку и все.

Not running for long, will break the shaft due to microcracking and thermal deformation. We did it and it didn't work.
