Hello All
I need to do a PQR / WPS with ASME section IX. I would like to have a WPS for GTAW and a WPS for GMAW spray. Both WPS with backing bar. No impacts, P1 to P1.
If I did a PQR with 1/2" thick plate with backing. Welded 1/4" thick with GTAW & 1/4" with GMAW. I would have a thickness range for base metal (T) of 3/16" to 1".
Filler metal is 2 x t.
Could I write 2 separate WPS with:
1) WPS with GTAW with backing, 3/16" to 1/2" thick base material. no impacts.
2) Another separate WPS with GMAW with backing, 3/16" to 1/2" thick base material. no impacts.
Thanks for your time.
