I'm a veteran cast iron welder and I have to say this guy is about as good as they come!I think he's using propane fuel which is the best way to go.I'm impressed!
This is living proof that the elderly can provide a huge contribution to society. The old master is living his twilight years in dignity in the firm knowledge that his skills are being passed down to the next generation. The rich industrialised nations disrespect the wisdom and knowledge of their elders which leads to fragmentation of the family support structure.
Most people watching this dont have the appreciation for this kind of repair.They just think oh hes just welding. Not understanding the difference with cast.I hope i can reach this level of repair before i die. Much respect.
Many years ago my grandfather told me that cracked cast iron engine blocks would be heated in a kiln to cherry red. Then the crack would be grooved and welded. The engine block was then surrounded by an insulating material and allowed to slowly cool over several days. He claimed these blocks were actually stronger then freshly cast blocks.
Well that gets a salute from me. The accuracy that the fill metal was laid down and the way it seemed to all hang together during the machining. The old guy has 'the touch'.
The guys from that part of the world are the best mechanics in the world.
Nice work, Pakistan!
Couple of things about this one. First, this is brazing not welding and it's the proper way to repair cast iron. Second if done right the repair will hold. Remember that when it was new the block was being held in the engine bay by a bolt which concentrates the stress in one small place, this brazed flange that he built up connects to the block in a much longer area so it's going to have a lot less stress on the material joint. But something else that isn't mentioned is it is quite clear they have been brazing on a LOT of these blocks because they had the slug made up in the dimensions of the crankshaft and it's seen a lot of pitting in between the mains so that indicates they have done this repair many times to this kind of block. I think it's clear the company that is casting these blocks is using crappy iron that's probably full of impurities, the blocks are crap, and suffer frequent failures and this shop sees them all the time they probably do one or two of these blocks a day.
I've been an engineer for 50 year. That is excellent workmanship with the tools available. A job well done. incredible welding. Cast iron is really hard to learn without getting cracks.
Now that's engineering on another level. It never ceases to amaze me at what these guys achieve with the tools they have.
Amazing craftsmanship! Super labor intensive but great outcome.
That is a legit cast iron block repair. Well done!!
I've been in Pakistan and watched these guys at work. Their craftsman ship is really awesome. All done with the most basic tools, too.
This guy has amazing skills, I thought I could braze, but he is the best I have ever seen
PAKISTANIS' GOT TALENT😍
Brilliant craftsmanship! An absolute pleasure to see.
It’s absolutely amazing what these people can do using worn out tools and poor working conditions.There talents are really something. Great video.
When i was teaching oxy welding we would teach then how to weld cast iron with super silicon the same as being shown here, it's 1 of them old skills that are being forgotten, kudos gent's from australia
Absolutely brilliant cast iron repair job 👏 😮 Good job Pakistan 🇵🇰 👍
In many places, that block would have been junked. It's satisfying to see these people working to give added life to this particular component.
