ASME UW-12 question
ASME UW-12 question
(OP)
I have a question ragarding UW-12 when head and shell are seamless. If I understood correctly joint efficiency E=1 when spot radiography requirements of UW-11a5b are met.
But if I preform no radiography or do not met above requirement E=0,85?
Also if one uses weld type no. 3,4,5 or 6 E=0,85?

For seamless sections, Type 1 joint, E = 1.0 for circumferential stress when UW-11 (a)(5)(b) is met.
E = 0.85 when UW-11(a)(5)(b) is not met or for Types 3, 4, 5, 6.
As UW-12 (d) states.
