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...
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?
