I'm fixing a crack in my header on my turbo regal. Should I mig or tig it. I can mig it myself tonight or give it to my friend to tig which may take weeks but be free. What would you guys do?
This. Drill a hole at each end of the crack and get the bitch good and hot before you weld it. Let it cool slowly.Believe it or not but old fashioned torch welding w/ good s2 filler wire would probably be the best and it may not crack again. Once it cracks it will likely crack again in the same area if migged or even tigged.
