This is in regards to an ALuminum welder certification I am trying to fill out.
You will need a copy of D 1.2 Structural Aluminum (2003)to help me, the other codes won't work.
I can't find the "thickness" qualification range for pipe/ tube for my welder cert.
I had a welder to a PQR for a 3/8" thick alum PLATE in the 1G position.
Table 3.3 Pg 23 lists plate and pipe position, that I got no problem. 1g and pipe is Flat, and per footnote 1, the diamater must be over 24", again no problem.
Table 3.4 pg 24 is the "number and range of thickness qualified." I don't see pipe listed as an option.
Does this mean he's not certified?
How can table 3.3 say he can weld it in the 1G position, but table 3.4 doesn't list a thickness for a test on plate?
I hope I'm misintrepreting this, any and all help would be appreciated, Thanks Chris
