UT testing
Thread Content
There is a statement on the drawing today stating that the fillet welds between fittings with a diameter of ≥80 mm and the head or shell must undergo recordable UT testing. I would like to ask everyone, how is this test carried out?
Additional non-destructive testing requirements generally apply to devices that are somewhat more important
Hello, more parameters are required for the flaw detection process. If you just want to learn about it, you can take a look at NB/T 47013.3 for ultrasonic testing
Traditional UT is not recordable; it should refer to TOFD. TOFD has become independent of UT, and this diagram is not accurate enough
You’ve misunderstood! I’m asking how such a test can be done.
