[MW:35748] Re: PQR- Chemical testing requirements

By Materials & Welding
As answered by everyone, chemical is not required.

Notwithstanding, please note that A-No. which denotes weld metal chemical composition is an essential variable, but carbon steel weld metal falls into A-No.1 only. 

Pl note your PQR will be valid only for those weld consumables which gives deposits matching to A-No.1 & 2 only, as per section IX.

1. What are the minimum testing requirements to qualify the PQR?

2. Is chemical testing required or not?

Thanks
