Thank you very much.
But, is that reason? I mean, is it the same difficulty, if a welder weld carbon steel and stainless steel?
distinction elsewhere in the asme code?
Thank you again
Hello,
what is the range of approval for a welder he tested in pipe with P-No. 1 to 1??
I think interpreting ASME IX, QW-423.1 following:
1 through 11, 34, 41 through 49.
Is that correct???
Can he welds, for example, P47?
Thank you
