Fillet Weld Procedure & Welder Qualification

admin

My employer has created a procedure for welding A36 to A36 using GMAW.   We have already cut the plate test specimens for the fillet weld test from QW-462.4(a).  I seem to be a little confused on which discipline to go by either AWS D.1.1 or ASME Sec. IX.  My question is this:  AWS says w1 should be maximum single pass fillet weld used in construction and w2 should be minimum multiple pass fillet weld used in construction in Figure 4.19 while ASME Sec. IX (QW-462.4(a) does not specify single or multiple passes for either weld.  Which one should I go by?  I have heard that AWS rules over ASME in this situation.....
Reply:Are you building presure vessles? I don't know if it matters but if you are then I would say asme code is king if no then aws d1.1.
Reply:The application of the WPS will dictate the code that you apply.Note that both these standards allow production fillet welding based on butt weld qualification. This is often a more cost productive route.Your comment about maximum single pass fillet leg or throat, minimum multi pass leg or throat is based on fillet qualification only to AWS D1.1. My suggestion is to qualify both codes via butt weld. There is a whole plethora of other considerations in both codes with respect to essential variables etc, however the scope of WPS development is far better based on a butt weld qualification.Cheers
Reply:I'd qualify the procedure in accordance with Section IX, and use a prequalified procedure to cover the D1.1 scope.
