Thanks Guys. As DekDee has pointed out, as the entire weld hasn't been completed by a single welder, he has to be qualified on a production butt with NDE or a performance qualification weld with bends. As our procedures are qualified in the 5G or 6G position, 4 side bends have to be tested which...
If 2 welders qualify a welding procedure (each welder does one half of the weld), and the weld is subject to radiography and mechanical testing as per ASME IX requirements in QW 451.1 do they have to carry out a performance test as per QW304?
Hi!
I have WPHY70, A694 F70 and API 5L X70 material to be welded to each other and also to P1 Group 1 and 2 materials. WPHY70, A694 F70 and API 5L X70 are all classed as P1 Group 3 in ASME IX but WPHY70 and A694 are not represented in Table A-1 of ASME B313. As they are not listed in B31.3, do...
Thanks Guys. ASME IX Introdiuction page states that "The toughness supplementary essential variables do not apply unless referenced by the Construction Codes". The Introduction does not indicate any reference to Client Specifications. I am a bit reluctant to apply the Impact Testing clause from...
As per ASME IX QG-105.2, Supplementary essential variables become additional essential variables in situations where procedure qualifications require toughness testing. QW-251.2 states that Supplementary essential variables are required for metals for which other Sections specify notch‐toughness...
I am planning to use a wps qualified with toughness testing. If this procedure is to be used for a weld which do not require toughness testing, is the group number still a supplementary essential variable?
