Metal Core Arc Welding
Metal Core Arc Welding
(OP)
I am curious as to how the AISC's prequalified weld tables deal with metal core arc welding. Is metal core arc welding another name for FCAW or MCAW? The prequalified tables only have SMAW, GMAW, FCAW . Thanks.





RE: Metal Core Arc Welding
This may be a nomenclature question but what exactly are you asking regarding metal core? Metal core could apply to SMAW - flux external, or solid wire core welding processes, GTAW, GMAW.

I was on the phone with a fabricator and I asked him what welding process they use in the shop so we can detail the shop drawings correctly. He responded by simply saying "Metal Core" ... I guess from dbooker's response, I will use the prequalified detailing of GMAW.

Review the Essential Variables for both, as related to the manufacturers recommendations
(and label on the wire)
They must be welding flat. or horiz., not sure thats a good field wire.
-Doesn't AISC refer you to AWS D1.? (for SS or CS) Structural?
