Welding mild steel bar into 52100 tube.

Postby JohnMc » Thu Oct 05, 2017 6:24 am

So I have to weld mild steel bars into the ends of a bunch of 52100 tubes. Have turned up some info on the internet. Recommendation seems to be 400-450F preheat weld with 7018 peen the hell out of it then a slow cool. Anyone have any other info to add?
