Sandeep,

The welder is qualified to weld s/s P8 using the GTAW because it is the same F No 6 .

The welder is not qualified for SMAW because the FNo are different C/S F No 4 E7018 the S/S is FNo 5 so he would need to be tested for SMAW welding.

YOU will need a PQR qualified for the S/S material as it is an essential variable but welders as stated above are OK.

Sandeep,

Please refer to ASME IX for a better understanding as the welder is NOT qualified to weld P8 based on P1

 

You will require a new PQR for P8

 

Thank you,

 

Best Regards.
