Hi,
Dear all members:
I've got problems understanding the following section !
I would deeply appreciate it if someone help me out explaining the fllowing paragraph with picture.
Thanks in advance.
b)For GTAW, SMAW, GMAW, PAW, and SAW,
or combinations of these processes, a PQR for a process recording a test coupon that was at least1?2 in. (13 mm) thick may be combined with one or more other PQRs recording another welding process and any greater base metal thickness. In this case, the process recorded on the ?rst PQR may be used to deposit the root layers using the process(es) recorded on that PQR up to 2t (for short-circuiting type of GMAW, see QW-404.32) in thickness on base metal of the maximum thickness quali?ed by the other PQR(s) used to support the WPS. The requirements of Note (1) of QW-451.1 and QW- 451.2 shall apply.
