Hello,
I would to try and combine two PQRs into a WPS.
PQR 1 is 3G with CVNs, materials welded API 5L X65 - API 2H Gr 50.
PQR 2 is a 6GR without CVNs, same filler metal as above only changing the materials (API 5L X65 - API 5L X52).
Intention is to have PQR 1 qualified for ALL positions. PQR 1 would have all the testing done (tensile, bends, CVNs, etc.) and PQR 2 would supplement this PQR with the positions. PQR 2 has the same filler metal, similar/same process parameters, etc. except for the base materials. Therefore PQR 2 would "demostrate" the weldability/penetration of the filler metal with the other variables.
Is this possible/feasible? Thank you.
