UCS-57 Radiographic Examination
UCS-57 Radiographic Examination
(OP)
Hello Everyone,
1).If Head(32mm) is Butt Welded(Full Penetration)with Shell(32mm), is this weld joint require FULL RADIOGRAPHY?
2).If Head(31mm) is Butt Welded(Full Penetration)with Shell(32mm), is this weld joint require FULL RADIOGRAPHY?

Thanks for your reply.
SectionIX: how it depends on joint efficiency???
David339933: Does UW-40(f)(1) "Nominal Thickness" apply for Radiography.because both 32mm butt weld will increase weld joint more than 32 mm.????
RE: UCS-57 Radiographic Examination
All things being relevant (non-lethal service, joint efficiency, and thickness) full radiography will not be mandatory. Joint efficiency is part of the calculation used to determine tmin, or minimum section thickness. A joint efficiency of 1.0 would require more radiographic testing that a lower joint efficiency factor. This is further explained in ASME Section VIII, Div. 1, UW-12.

Not sure I understand the question. UW-40(f)(1) - states the nominal thickness is the total depth of the weld EXCLUSIVE of any reinforcement. A 32mm buttweld to a 32mm buttweld would result in a 32mm thick weld. Reinforcement is not included.
