Kix,
myself never used prequalified WPS listed in section 3 of D1.1 before.
but try to give some points here
AWS D1.1
3.3 Base Metal/Filler Metal Combinations
Only base metals and filler metals listed in Table 3.1 may be used in prequalified WPSs. (For the qualification
of listed base metals and filler metals, and for base metals and filler metals not listed in Table 3.1, see 4.1.1.)
4.1.1 Welding Procedure Specification (WPS). Except for prequalified WPSs in conformance with Section
3, a WPS for use in production welding shall be qualified in conformance with Section 4, Part B. Properly documented
evidence of previous WPS qualification may be used.
if your filler is not listed in Table 3.1... u cannot use prequalified WPS listed in section 3.
Please correct me if i'm wrong.
Best Regards,
Noel Tan
