Re: [MW:35412] minimum thickness for Ultrasonic Testing (UT).

ASME Sec IX
QW-191.2 Ultrasonic Examination
QW-191.2.1 Method
(a) The ultrasonic examination in QW-142 for welders
and in
QW-143 for welding operators may be conducted
on test welds in material
1∕4 in. (6 mm) thick or greater.
(b) Ultrasonic examinations shall be performed using a
written procedure in compliance with Section V, Article 1,
T-150 and the requirements of Section V, Article 4 for
methods and procedures.



Thank you, 
Regards, 
S.SENTHILKUMAR

While ASME doesn't explicitly state a minimum thickness for weld plates undergoing UT testing, practical limitations and industry best practices generally dictate a minimum thickness of around 6 mm (1/4 inch).


Important considerations:
* ASME Section V, Article 4: This section provides guidelines for ultrasonic examination procedures, but doesn't specify a minimum thickness.
* Code cases: Some ASME code cases might allow UT on thinner materials under specific conditions.
* Other standards: Other standards, such as AWS D1.1 for structural welding, might provide guidance on minimum thickness for UT.
* Practical limitations: The actual minimum thickness that can be effectively inspected by UT can depend on factors like the material type, welding process, and the specific UT equipment and techniques used.
It's crucial to consult the relevant ASME codes, industry standards, and qualified NDT personnel to determine the appropriate minimum thickness for UT testing in your specific application.

Dear All,

What will be the minimum thickness of a weld plate required for UT testing as per ASME?  

Thanks,
