We have a FCAW process PQR that covers a range of material thickness of .187" to 8".
If we qualify a coupon using GTAW process using 1/2" thick material or greater we will be allowed to combine these 2 PQRs to write a WPS that covers a root pass and 2 additional fill passes using GTAW and the balance of the fill passes and cap using FCAW up to 8" material thickness??
Am I correct in my interpretation of the code as stated below??
ASME sec IX QW-200.4
(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 least 1⁄2 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
first PQR may be used to deposit the root layers using
the process(es) recorded on that PQR up to 2t (for shortcircuiting
type of GMAW, see QW-404.32) in thickness
on base metal of the maximum thickness qualified by the
other PQR(s) used to support the WPS. The requirements
of Note (1) of tables QW-451.1 and QW-451.2 shall apply.
As per QW200.4(b) the GTAW PQR must be 1/2" thick or more
