AWS D1.1 Welding Procedure Qualification
AWS D1.1 Welding Procedure Qualification
(OP)
Can somebody explain the following code to me?
AWS D1.1 (2008) Table 4.5 (PQR essential Variable changes requiring WPS Requalification.......) Item 33:
A Change exceeding the tolerances of 3.12, 3.13, 3.13.4, 5.22.4.1, 5.22.4.2 involving:
(1) A decrease in the groove angle
(2) A decrease in the root opening
(3) A decrease in the root face
My question:
(a) Sections 3.12, 3.13, 3.13.4 are used for prequalification. Based on Table 4.5, they are also applied to tested welding procedure qualification, right?
(b) Suppose we use single-V-grove butt joint, FCAW (B-U2-GF) in PQR. Groove angle 45 Degree, Root opening: 5mm, Root Face: 2mm. What is the qualified Groove angle; Root opening; and Root Face?
(c) How to use the above (b) condition to qualify a fillet welding? Do we need consider the joint design as a essential variable for a fillet welding?
Thanks

RE: AWS D1.1 Welding Procedure Qualification
I'm not 100% sure what you are asking. Do you want to qualify a procedure for fillet welding? What makes your procedure non prequalified?
