Thanks,
But in my case, the contractor use in all WPS and PQR form the electrode clasification in lieu of A-nummber or chemical composition as permitted by QW-404.5?
Exactly, in the WPS for GMAW and GTAW rods, they put into the form ''ER-70S-6'' in lieu of A-number and chemical composition. I think that the correct interpretation is that you can use the AWS specification as reference to the chemical composition, but in any case you can put into the form the AWS specification (ER-70S-6) instead the A-number or chemical composition.
that is the problem I have, and according with that paragraph they thinking is allowed.
I would appreciatte any knowledge you have,
