Guys AS/NZS 2980 is specific to Welder Qualifications and it clearly defines all the essential elements of WQs.
there are no grey areas as is the case with the AS/NZS 1554 series. 2980 details material thicknesses qualified for butts, fillets and lists pipe dia. Refer to Tables 2.7 (A), 2.7 (B) and 2.7(C) .It also includes the thickness range for single & multi-process joints for butt welds Table 2.2.& 2.9 (A)
It clarifies the range of qualification for welding consumables and list the requirements for fillet welds qualification for single and multi-layer welds. Table 2.9 (B).
NDE & DT are more comprehensive and this gives greater satisfaction in regard to the integrity of the joint with a fracture test and/or at least two Macro for fillets and RT and bends or fracture for Butts.
I would much rather see all refernces to WQs removed from the 1554 series and WQ done strictly to 2980.
AS/NZS 1554.6 S/S Structural is a beast and 2980 can make your life considerably more comfortable from a WQ perspective.
