WPS w/ one process qualified by a PQR 2 processes

(OP)
Dear All,

I'd like to request your help on the following subject:

 - I want to qualify a WPS for one process (GTAW)according to ASME IX, with a PQR for two processes (GTAW+SMAW). In the deposit metal thickness range t (QW-404.30) I've to apply the table QW-451, but for base metal thickness range T (QW-403.8) I've to put the same range of the deposit material t, or is better don't define?

thanks in advance

Look at QW-256, essential variables for welding using the GTAW process.
