Stop in for a cup of coffee

Yep, I have seen it done with exhaust manifold studs. There's a guy locally that has a portable tig welder that does that. He shows up and extracts broken bolts and studs. $100 for the trip and the first extraction. $50 for each additional. Cheap at twice the price.

I do them with a TIG as well it is much easier. I build up a little tit then when I am above grade a weld a washer on, then weld a nut to the washer. When I pull off and the nut is Cherry hot I cover it in a cold wet rag to get some shock and shrinkage. Then screw em out easy peasy. Holy crap I just read that back and thought Karl is going to fillet me!
