Hi,
No need to specify the Chem.of Weldmetal in PQR. This essential variable is to make sure that you are using the correct chemical composition of weldmetal/Filler rods.So you have to check the Welding consumable certificate with the Sec.IX table QW-442 to the corresponding A.No and confirm the A.No match with the Type of Weld Depoit.
Thanks & Regards,
(Karthik)

Thanks. Let me clarify further. I agree that A No needs to be mentioned in PQR but, Is it required to carry out weld metal chemical analysis and describe the chemistry in PQR? Is any requirements mentioned in ASME B 31.3 regarding this?

Does Weld Metal Chemical analysis (A No.) is an essential to be mentioned while qualifying PQR for meeting ASME B 31.3? Please let me know the clause if possible mentioning the above details. Regards, Jaydeep --
