So your saying he's the only one that knows what he's doing? I've been at this for 20 years now buddy. If you read the initial post from the OP he states the bolt is too far down the hole to weld a nut to. Its also cast heads so trying to build up weld inside the hole will just fuse the nut to head and make a worse situation.

Not true with a Tig Welder even if it is busted off past the flush point. You have so much control over the weld puddle/heat that it can be done without fusing it to the cast material...... the tungsten tip will fit right down in the hole easily . Just something to think about is all. Every situation is different. Location etc plays a big roll in how to approach it.

I have done it the way I have explained and it works perfect. The ez out busted off just like the OP's situation and everything. No reason to get all hostile over it........:D
