We have a Client that we are building a non-stamped vessel (under 15psig and non-lethal and 1/2"-5/8" thk) to ASME Section VIII Div 1.

Client has stated all welds in material ½ in. (13 mm) and greater in thickness may be examined using the ultrasonic (UT) method given the requirements of 7.5.5 of Section VIII, Div. 2.

Not having access to these requirements, my question is, "Is manual shearwave UT method acceptable?"

Thank you for your assessment and comments.

Found answer to be No, shearwave is not acceptable method of UT for Div 2.

The conventional manual share wave no.
Share wave is acceptable but it cannot be manual but mechanized and recorded.
Phased array is a technique using share waves.
TOFD (Time of Flight Diffraction) is a mechanized system different from the conventional pulse echo.
