welding procedure qualification
welding procedure qualification
(OP)
Hello frends,
Please help me on the below subject
Reference to ASME SECTION IX-QW-420-1 P Numbers
To reduce the number of procedure qualifications required base metals have been assinged P Numbers,
P-No.1 Through P-No.11 Including PNo.5A,5B and 5C
My interpretation is A welder qualified on P1 is qualified on P1 to P11 and P5A,P5b and P5C
Please correct me if I am wrong
Thanks,
pojo

However if the process were GTAW using F-6 Filler metal you would be qualified for ERxxSX and ER3xx both of witch are F-6.
An exception to above would exist if the welder qualification test were done on Stainless with an open root and purge gas was used. That welder would NOT be qualified to weld a root pass on Carbon Steel unless it was purged.
Hopefully I didn't confuse things:)
Have a nice day

SMAW
What happened to using 309 electrodes to weld P1-P1 material and 6010/7018 to weld P1-P1 material thus be qualified for all materials, P1-P11?
This is our standard welder qualification and has been for years. In fact we initially used 310 in lieu of 309 SS electrodes prior to advent of decent 309 electrodes, which did cause a few welders problems, but the great majority would pass if they keep the heat input low.
