Hello,
I'm trying to figure out how to qualify a tack weld procedure for work we are doing under B31.3 normal fluid service piping. It is basically for fitting up stainless pipe using tabs that will be broken off after welding, I wanted to qualify a procedure using short-circuit gmaw to save time- we've been using gtaw up til now.
Under QW 202.2(c) it says that a fillet weld test can be used for procedure qualification, and then refers to QW 462.4(a) for preparation of test coupon for getting macro etch specimens. There is nothing about break testing or bending or any other kind of mechanical testing. Does this mean that all I have to do to qualify a fillet weld procedure is to do a fillet test and get the five macro specimens??
