Yes it is permitted from year 2010 edition (If you are asking for ASME BPV Sec IX).

Generally where the term "radiography" or its derivatives have been used in Section IX in the past, the phrase "or ultrasonic examination" has been added

or "volumetric NDE" is used. The acceptance criteria are similar to those for radiography. The big limit on using ultrasonic examination on performance qualification tests, however, is that the coupon or production weld must be ½ inch thick or thicker.

Forms QW-484A and QW-484B have been revised to add a check box choice of RT or UT when volumetric NDE is performed.
