The heat from the welder helps loosen the rest of the bolt stuck in there. I've never done it but we have a mechanic that can do it. He has a failure rate of about 2%. He taught himself how to weld by watching KZbin videos.

Yes Sir! 1-the nut gives you something to grab onto, and 2- the heat works it's magic

You actually have to wait until the bolt cools down a bit. Heat expands metal. And the bold will expand when welded.

Got to be careful welding to a zinc coated nut or washer like that… the welding fumes contain zinc oxide which you don’t want to breathe.

if the bolt broke don't you think the poor at best weld will break? aren't you welding the bolt to the hole? One other guy talks about putting a copper sleeve in the hole first.

[@jedlowdually]

@salvor1 An exhaust manifold bolt will break from the repeated thermal expansion and eventually just gets sheared off. Once the head of a bolt is broken off the remainder of the bolt/threads no longer has tension on it, so quite often to get it out you just need to attach a handle=welding on a nut

The head is aluminum in this case. If it was cast iron you would need to be careful not tonweld to the head, but it still works the same.

I have three in the exhaust to do, but they’re all about a half inch down in the hole. Not sure if I can use my welder for that one.

[@alexward8596]

do you absolutely need the washer or just depends on the situation?

Why the washer I have seen people use a washer in between but I assumed that was like a buffer to slide easier or something but watching this I can only assume is it is easily to get the washer welded then weld the nut to the washer, I juat use a nut and it generally takes 2 trys with a flux core welder so maybe I'm wrong

[@jedlowdually]

@james10739 If the broken bolt or stud is broken too far down you may lose too much heat trying to weld to a nut. Welding 1st to a washer gets you the thickness of the nut closer to the broken bolt so you have a better chance of welding to it, then once you do it's easy to weld a nut to that.
