Field welding sch. 40 2" and below
Field welding sch. 40 2" and below
(OP)
Hi,
I was told that if thin wall pipes like sch. 40 and less if stick welded only, they may not be able to pass x-ray, and the other welding process like MIG, etc may not be easy in the field where stick welding is popular because of equipment type.
Is there any variable that can change like: Choice of electrode that can make it possible and better to stick weld thin pipes in the field?
Thank you.

Pipe material coule be: A106 A, B. x-42, x-52,... BUT MOSTLY A106 GRADE B.

Concurr that GTAW is a superb process. Somewhat slower than SMAW. *Not* a lot slower. [this is counter to most texts, but has been my experience in the past 32 years].
GMAW is not really a field process, unless the diameter gets above 12" or so. Still not much faster than SMAW, due to set-up time and the requirement for draft shielding.
