Welding Procedure Qualification

admin

Dear all,I have a confusion regarding WPS and PQR as per ASM section IX. I want some help from you.I have qualified a welding procedure of a butt weld having plate thicknesses of 8 mm i.e. (T1=8mm & T2= 8 mm), material is stainless steel (SS 304L) and process is GTAW. I then developed WPS based upon the qualified welding procedure.Now I have to make two fillet welds of same material having following thicknesses:Fillet weld 1: T1=28mm and T2=8mmFillet weld 1: T1=8mm and T2=2mmNow my questions are:1. Should I qualify a welding procedure for fillet welds separately or I can use the same PQR for butt weld to make a fillet weld?2. If I am going to use the same PQR for making a fillet weld then should i use the same parameters that are mentioned in PQR or the parameters could be different? i.e. WPS for fillet weld should contain the same parameters mentioned in PQR of butt weld or it could be different?
