We'll use a combination of resistance heaters and induction heaters, but still we can't heat the weld itself, cos access is very cramped.
Thanks for the tips everybody!
To prevent stress corrosion cracks in a weld we do a post-weld heat treatment. The material is a simple low carbon (approx 0.2% C) and low alloy steel. Due to the big size and complicated shape of the object we can't heat the weld itself. To make sure that the weld itself sees a temperature high...
