Many thanks metengr
So only A-No's 1 & 2 can be interchangeable, in my case A-No's 1 & 11 cannot, so we have to qualify another procedure if we wish to change the filler metal from ER80-D2 to ER70S-6.
Thank you

Thanks for the reply.
Our welderqual software has this as A-No 11
Please see below link.

Thanks for the help with this metengr.
So with the A-No's being 1 & 11 they are still interchangeable because they are in table QW-442.
ER70S-6 F-No6 A-No1
ER80S-D2 F-No6 A-No11
And for ferrous materials. A-No's 1-12 are interchangeable if in the same F Group?
Apologies for the continued...
From what at I have looked up,
According to Table QW-256 the change in A-No is an essential variable so I would need to re-qualify a procedure if i wanted to chance the GTAW filler wire.
Hello all,

Can this procedure be used for the X52 pipe as both are P-1...
