For welders qualifying for the ASW classification, is visual inspection of the weld the only method used to evaluate the test assembly?

• A. No, additional mechanical testing or break tests are used.
• B. Yes, only visual.
• C. It depends on the employer.
• D. Visual inspection is not used.

Answer: (A)

Visual inspection alone only checks surface appearance and workmanship; it can’t reveal hidden internal flaws or confirm that the weld will actually perform under service loads. For ASW qualification, the test assembly is evaluated with more than just a lookover. Mechanical testing, such as bend or break tests (and other specified tests), is required to verify the weld’s strength, ductility, and overall integrity. If those tests don’t meet the acceptance criteria, the welder does not qualify. This requirement isn’t left to an employer’s discretion—the standard calls for both visual assessment and mechanical evaluation to establish qualification.
