Weldability
Weldability
(OP)
Hello,
I am sure many threads might have been posted already on weldability carbon equivalent calculations. I have looked in to them but can not find what I am after.
I am looking for specific info on when one particular equation can be used, such as what type of steel and composition limits. Say for ex. Pcm say max carbon ~0.10%.
Why? I would like to not use the IIW formula for everything (in my case low alloy steel castings C-Mn-Si-Ni-Cr-Mo) and interested in the background how these were developed.
Cheers

jwhit, I work with the foundry and while specifying the weldability of the casting with 0.2C I ran in to trouble as CE-IIW equation gives greater values. other question I have is CE-IIW equation does not include Si in them.
