Is it permissable to perform a welder qualification using a P1 to P1 welded with inconel when the supporting PQR was performed in P1 to P8 and welded with inconel.
Thanks in advance.

Is it permissable to use a Dolly-mix (Vertical up GTAW / SMAW - Vertical Down) Groove PQR in P1 Group 1 (Without notch toughness)to perform a vertical groove weld? Code is ASME IX, with no application standards
Thanks

Reference Chapter V - 328.2.2.f
Is it permissable to allow STT Root & FCAW when B31.3 applies? It seems that clause QW 328.2.2.f relating to fluid piping forbids this? Is this only applicable when using a PQR qualified by 'others' and not the manufacturer?

Hi All
Regarding ASME IX is it possible to split a multi process PQR, i.e GTAW (Root & Hot Pass) & SMAW (Cap & Fill)? Thus enabling the GTAW process to be used seperattly from the SMAW?
Thanks in advance
Hi All
Could someone help me out with the Upper Transformation Temperature (AC3 Temperature) for ASTM A335: P5 material. This is a 5%Cr / 0.5% material.
This query is in relation to a welded joint which requires PWHT. The PWHT will affect the thickness approval ranges.
Many Thanks in...
