ASME welder Qualification
ASME welder Qualification
(OP)
To start with I'm a fromer Navy NDT inspector and ASME is really a lot less restrictive. I'm in a learning curve. LOL
My question is where exactly are the acceptance information of a welders qual? I really didn't see out right accepatance in the Sec. IX or V. I'm trying to detremine max weld reenforcement on a welders butt weld qualification. Thanks for the assistance.

Fizza is correct in that Section IX does not provide the acceptance or rejection of welder qualification on the basis of weld reinforcement.
Other codes of construction will dictate the reinforcement of girth and longitudinal butt welds such as ASME B31.1 Power Piping Table 127.4.2 that takes into consideration maximum thickness of reinforcement based on design temperature.
An example from such table is thickness of base metal over 1/8" to 3/16" incl. is 1/16" for temperatures >750 deg F; 1/8" for temps 350-750 deg F; 3/16" for temps <350 deg F.

Question (2): If the welder is testing under a code - for example, ANSI/ASME B31.1 - is the
supervisor conducting the tests supposed to base his visual requirements on the production weld
visual requirements listed in ANSI/ASME B31.1?
Reply (2): No.

I tell the welders that ar testing what MY minimums and maximums are. If I know that he/she will be working on B31.3 only, those limits are generous. If I know that he/she will be working predominately Sect I and/or B31.1, I inspect to those, tighter, values. After carefully and clearly informing the testee.
