Dear, 

If the company used different brands of wire in a single test coupon,  then it can be considered as a change of variables like process, filler wire etc, as per QW-202.2(b).  In this case, the deposited weld metal thickness for each brand of wire shall be noted and the range of values arrived at using the table QW-451.1

Hope this helps.

Gents,

I have encountered a WPS where manufacture used different brands of SAW wire and flux in single PQR to cover the range of various brand.

Is it permitted to qualify a single PQR with different brand in same weld ?

We can make separate PQR with each brand and can combine those PQR in a single WPS. But welding a single coupon using different SAW fire /flux combination is not yet experienced before. Could you please shed some light on this scenario ?

Plate : SA 516 Gr.70, 

Wire F7P8EH12K :  ESAB/LONCOLN/Bohler

Thanks & Regards
