For our qualifications PQR (last done in 2012) to cored wire for carbon steel, we use the wire classified SFA / AWS A5.20 E71T-1M.
Today we received from our supplier wire classified SFA / AWS A5.36 E71T1-M21A0-CS2.
The classification QW-404.12 is different, we have to issue new qualification?
Qw-404.33 has to be displayed in WPS process in GTAW. If i changed the material i don't need the requalification but how I have to type in WPS. it is not applicable (N.A.) or not used ( Not Used )
