WOW!!! I'm sure most viewers won't appreciate the trickiness of this task. 25yrs I had a friend whose head cracked on his XS500 motorcycle. We looked around for a replacement but due to the relative rarity of the machine one could not be found for love or money. At the time I worked in a well equipped fabrication shop so I was asked if anything could be done. There was also a well equipped machine shop right next door. I had a look and said "No way". Due to the brittleness of castings, the heat stresses involved,.the concominant distortion and the precision required the job was seen as almost impossible and even if successful it would be likely to crack again soon after. I asked several of my coworkers and they agreed with my opinion. But as there was NO other option we tried it anyway. One of our most experienced welders tried it and the head just cracked somewhere else as soon almost as soon as the torch was applied even though we had carefully preheated the head. So, even in our first world hi-tech fully equipped workshops this job could not be done. Yet here they are actually achieving it on the backstreets of Pakistan, and with primitive equipment. I believe the trick was to do the welding while keeping the head in the 'oven'. Ingenious, I really take my hat off to these guys.

I haven't seen anyone using cast iron fusion welding in the last 50 years other than myself and then I only used it twice. It's nice to know that someone somewhere is still using it. In todays market it had been largely displaced for faster are welding methods. Dumb thing is it was still better than anything out there today.

I've heard of using pure nickel, nickel-iron alloy rod and cast iron rod. I'm guessing they're probably using cast iron as that would be the cheapest option.

[@autophyte]

This is how cast iron welding was done in the old days,-Grind or chip out the crack, preheat the job in a charcoal furnace.Using a cast iron welding rod with flux (usually borax), fuse the rod into the hogged out crack, it's absolutely crucial that you let the job cool down SLOWLY- 6 hours at least,If you don't, unequal contraction will cause the metal to crack again, I've repaired many cast iron jobs and I still have a couple of rods in my garage. Nowadays, people use electric welding, using nickel rods, and peening the repair as it cools, to prevent cracking, but cast iron welding is still very risky,due to the of cast iron. It also is porous to a degree, and oil in the matrix will prevent a successful weld being performed. , ;

That alignment stub that goes into the valve guides to enable the valve seats to be concentric is a little bent and the cylinder head should not rock as it does when doing that operatio0n now and later on when cutting the valve seatings. I do not like how he pushes on the head at 16:21, and I shivered at some other actions he took during other operations, but then perhaps I am too fussy and a cylinder head need not be coaxed and treated with gloves as I thought it should. The welder was brilliant in every way and that man knows the phase diagram of that metal he was handling. He is not only intelligent and feels his way through, but he is also a very brave man to handle that little bit of welding procedure!!!!! It is such a pity that our education system does not give enough credit to these people who have the ability to " process" an issue rather than remember information. Most people these days are the proud owners of what they buy and operate and not what they can process and diagnose an entity that needs to be repaired and guaranteed. Such craftsmen do not need any examiner to judge their caliber as the result is in the guaranteed working of the item they produce. Many schools run curriculums where the school thinks that its own examiners will decide the caliber of its students, but real life is not like that........................... our real value is what we can produce and guarantee to work without nature nor luck ever giving us a hand!!

@@rrezaputrap2862 cast iron tends to be brittle. If it cools abruptly, it will crack or break. Same for any sudden changes in temperature. Hence, one wishes to heat pieces of it well - say, 8-900 degrees F, or 500 or so C - and keep it at that temperature while being welded or brazed - and then cool slowly, so that the stresses will *hopefully* equalize in the part as a whole. The ductility of “brass” is why brazing is often favored. Cast iron welding, however, has its advantages, which is why some still attempt to do it.

Wow. Strictly speaking he recast metal rods into a pre-soaked (already red hot) cylinder head using a gas torch to melt and reflow the two metals together. I guess this has similarities to how old lead plumbing was undertaken with new just about molten lead being applied to lead which is just shy of melting point in order to fuse the two metals seamlessly together! Takes a lot of experience to be able to work metals in such a way without applying too much heat to the solid metal (melt your work) or too little heat to old and new which won't fuse the two together! My main worry would be that in attempting such a repair the water channel was closed off or narrower than before resulting in under cooling part of the engine under load! Let alone as others have said the wonky drill press with the very large runout, or the angle grinder being taken to the head several times over to nefarious places before flattening - which must mean the head had to be ground down excessively to make it flat again!

[@javeedsultan8484]

In todays high tech western society these guys wouldn't even qualify to start a course. But in the real world I'd back these guys all day long. In the west we've lost the ability to ask What If?. Everything nowadays has a procedure to follow,

That engine head is now ready to run for several years, she's rescued, not trashed and swapped for new : no wasting 👍

[@cohall46]

These videos are so captivating - trying to figure out what the guys are going to next and how they re going to do it.

[@deekaxel8760]

Where has this head been repaired? India? Unbelievable how skilful this man did the repair. I am speechless.

A calliper would be easier than a measurement and a screw gauge. South East Asia has been at the fore front of metallurgy since the bronze age so no surprises here. Excellent work on the weld. Respect from India

[@brandonw5356]

Coming from a mechanic this is what’s wrong with most of the rest of the world people have forgotten how to do things the hard way by hand. Now they just log on and get what they want. That head will probably seal better than any new head you can buy offline. Keep the forgotten arts alive guys.

Минимальными средствами делают сложную работу. Отлично! На западе потратили в 1000раз больше для этого. С уважением.

[@ruslanbulgarski7932]

ошибаетесь, это уже было бы на переплавке, чинить такое не то что на западе, даже у нас в России не имеет смысла. Даже тиг сваркой сложно сварить без микротрещин, а тут трещинки недопустимы
