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

RE: Weldability

Often the Material Specification or the Construction Specification will give you the formula to use. For ASTM materials it may be listed in the Supplementary requirements. If building a NACE compliant component their formula will be found within the specification. Regardless, the formula that applies should be hidden within the PO requirements, either by reference to a supplementary or to NACE or whatever spec's they dictate. It can take a good bit of time to track everything down.

Thank you all for the responses. Corypad, I have seen the link it is a pretty good one. Metengr, I will go through the document thanks!
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.
