As such, per QW-301.2, "The performance test may be terminated at any stage of the testing procedure, whenever it becomes apparent to the supervisor conducting the the tests that the welder or welding operator does not have the required skill to produce satisfactory results."Īs per VPL. Also refer to QW-302.4, "Pipe coupons shall be visually examined per QW-194 over the entire circumference, inside and out."įinally, per QW-301.1, "The performance qualification tests are intended to determine the ability of welders and welding operators to make sound welds. Obviously, the root must be accessible for visual examination and would not be required on production weld qualifications. QW-142 states, "Radiographic Examinations may be substituted for mechanical testing." Visual examination is still required per QW-144 and QW-194 (complete joint penetration, complete fusion required) when RT is used in lieu of mechanical tests. There is no requirement that a Level III in the RT method sign off on the RT report in ASME IX nor in the B31 Codes referenced previously. RE: welders test stanweld (Materials) 14 Dec 09 16:40 Please see FAQ731-376: Forum Policies: Forum Policies for tips on how to make the best use of the Eng-Tips Forums. They obviously work on your computer (though perhaps they stick) as you use them to put in excessive punctuation. There are shift keys that let you make capital letters. Here's another piece of "good information" that you probably don't want: Using proper grammar and punctuation helps you be taken seriously. (Though I don't know what API1104 requires and I don't know what your project requires). I believe that the ASME Code requires a Level III NDE inspector sign off on welder qualifications and there are certain requirements to become a Level III inspector. However, your questions appear to indicate that you do not have the required knowledge to verify the acceptablity of someone else's work in the QA/QC field. I am not in the least questioning your competance as a mechanical engineer. I take it by "good information" you mean only information that lets you do what you want and not information that tells you it's a bad idea. Only if you have any good information please write it?
