UT for Cat D welds - ASME VIII Div II
(OP)
Hi,
According to Table 7.2 of ASME VIII Div.II, for Cat D joints, either type 1 or 7, RT or UT is required, together with MT or PT. My question is whether the UT shown in Table 7.2 is "in lieu of RT", or conventional UT could be performed.

RE: UT for Cat D welds - ASME VIII Div II
please have look on table 7.2, which indicate for
-type 1 weld: UT per 7.5.5
-type 7 weld: either UT per 7.5.4 or 7.5.5
Paragraph 7.5.4 is the applicable paragraph for conventional UT
Paragraph 7.5.5 is the applicable paragraph for UT in lieu of RT (PA-UT or TOFD-UT)

I was looking exactly for this, and just realized that Code edition 2017 is much more clear than edition 2015. In ed. 2017, note 1 of table 7.2 is self explanatory, while in edition 2015, this was a grey area... Of course, there is always table 7.3, which is one page after... So far away... I should have seen it! Thanks, fleischfresser, once again!
