Hi everyone, long time stalker first time poster!
I'm helping my brother out with his car @biddie_fiddler as it's hit the sh*t a bit lately. I am going to reclaim and re weld the external waste gate from one rear housing to another. I am a welder/fabricator by trade and I weld exotics/alloys as well as regular carbon steels, however I have never cast, let alone steel to cast. My question is going out to those who have done it before, I know that cast needs pre and post heat treatment however I know that no one does that, what filler wires did you use and how did you do it without it cracking? I am thinking I'm going to use inconel wire as it binds nearly every dis similar metals together. Please tell me how you've gone about it?
