If you qualify a welder to a B-U2-GF joint design (Single V groove weld with backgouge / weld), does this also qualify the same welder to a B-U2a-GF (Single V groove weld with backing material) in production welds under the D1.1 or 15.1 specification?
See this thread. http://aws.org/cgi-bin/mwf/topic_show.pl?id=3304 and read the statement that refer to the test plate details 4.21 and 4.22 I think.
Have a nice day
If I'm not mistaken, if you add backing you don't have to requal. If you remove backing, I tihnk you do. Don't have D1.1 in front of me, but I tink I read that one before.
