A588 with 80 filler procedure question?
(OP)
If welding a588 that is going to be exposed, bare weathered, multi pass groove with E8XTX A5.29 filler metal for atmosheric corrosion and weathering characteristics, can this be done with a pre-qualified wps?
A558 is a group II material, therefore can you write a wps just for A588 welded with 80 series filler or would you have to produce a pqr?Table 4.5 PQR essential variable changes - filler metal 1) Increase in filler metal classification strength.
BUT, Table 3.1, A588 with note b Special welding material and WPS(e.g. E80XX-X low alloy electrodes) may be required ect. ect.
So does that mean that you can write a WPS prequalified to meet the requirement, or does a PQR need to be performed, I'm a little stumped...
Thanks for advice/comments,Robert

Provided that your weld falls with parameters of Chapter 3; base metal, filler metal, welding process, preheat, etc. So that all parameters are prequalified, then your WPS is prequalified and does not require physical testing. I believe in your case all the parameters are prequalified.
To give proper credit, I also asked the Chair of D1.1 and he clarified my poor understanding.
