    ASME IX and Socket welds

    Don't get lost in the differences between Procedure and Performance Qualifications. QW451 deals with Procedure Qualifications, QW452 deals with Welder Performance Qualifications. As "metengr" pointed out earlier in this thread, QW451.4 allows for any size fillet weld to be made with a Procedure...
