P91 - Welder qualification
ASIF
WAGNER Daniel
Dear AISF,
Please refer to ASME Section IX, paragraph QW-423.1:
Welders qualified using any P-No. 1 through P-no. 15F, P-No. 34 and P.-No. 41 through P-No. 49 are qualified for production welding of same. Therefore, yes, he would be qualified for A335 P91 materials without further qualification. I would however, caution that you need to ensure the welder understands the requirements of welding P15E materials and that there is a qualified procedure acceptable to product and service conditions.

Dear All,
We have qualified procedure for Inconel 8825 P No. 45 as per ASME Section-9 with GTAW process using filler ErNiCrMo3, now we need to weld Inconel 625 P No. 43 with GTAW using the same filler i.e. ErNiCrMo3. Please suggest if we can use already qualified procedure for Inconel 825 for Inconel 625 also or we need to do the fresh qualification for this.
Thanks in advance for your kind help.
With kind regards,

You have to go for different PQR , as P No. is different , which is essential variable as per ASME IX

Please review QW-350 (welder qualification), change is P no. would require requalification regardless of welding process.
