Hello Everyone, find the solution to my query with respect to ASME Sec. IX.
PQR A is qualified in 9.53mm base metal thickness with 4 mm (TGx308L) & 5.53 mm(ER308L) of weld deposits in GTAW process. PQR B is qualified in 20 mm base metal thickness with 7 mm of GTAW & 13 mm of SMAW weld deposits (ER308L+ E308L-16).
Can I generate a single WPS of GTAW +SMAW with Electrode combination of TGx308L and E308L-16, and weld deposits. kindly give your feedbacks.

Thanks to all in advance.

You can use the two to permit qualification from 1/16" (1.6 mm) to 40 mm. I'm not sure why you really want to do so but you can.
 
To avoid purging requirement in some joints we need to qualify this WPS and Welder.
