The statement 'Discontinuity and flaw are the same thing' is:

• A. True
• B. False
• C. Not necessarily
• D. Unrelated

Answer: (A)

A weld discontinuity is any irregularity that deviates from the intended weld shape or fit-up, and it covers a wide range of possibilities—from tiny, acceptable porosity to larger imperfections. A flaw (or defect) is a specific type of discontinuity that fails to meet the applicable code or specification and is considered unacceptable for service. Because some discontinuities are permitted within documented acceptance criteria, while others are not, they are not the same thing. In practice, an evaluator uses the code’s acceptance limits to decide whether a particular discontinuity is a flaw that requires repair or rejection, or simply a permissible imperfection.
