Please offer your opinion on this. I have a situation that I need to resolve. Does the following seem right to you?
As a general rule, welds are either pre-qualified or qualified by test to ensure that it is possible to achieve a solid weld using that specific joint configuration. If every joint on the jobsite that is welded is prequalified, very little or no non destructive inspection may be necessary. If a joint is welded up, but it is not a pre-qualified joint and has not been qualified by testing, then it would be necessary and would be acceptable to inspect by means of non destructive testing such as UT every similar welded joint to ensure that the weld is acceptable per AWS. Meaning that because the weld doesn’t have any discontinuities greater than the max acceptable per AWS, that the weld is essentially a solid weld, despite not having been a qualified weld.
