Is it possible to MIG weld an exhaust maniford stud to a cast iron head on my Jeep? The existing stud was broken off and cannot be drilled out. Suggestions on wire and settings?
There was a link to a video on here I think it was. The guy mig welded a mild steel nut of the same dia as the snapped stud onto the end of the snapped stud by placing nut centrally over the stud end (nut flush on face of the head or flange surface) by pointing the mig wire down inside the nut onto the end of the stud. The heat loosened the snapped in stud easing it's removal with a spanner on the newly fixed nut.
