A discontinuity is the same as a flaw.

A discontinuity is the same as a flaw.

• A. It is always a flaw
• B. It is never a flaw
• C. A discontinuity is the same as a flaw
• D. It is the opposite of a flaw

Answer: (C)

Discontinuity and flaw are not the same thing. A discontinuity is any interruption in the material or weld that breaks its perfect continuity. A flaw, on the other hand, is a specific type of discontinuity that does not meet the required acceptance criteria and is treated as a defect. Some discontinuities are permissible or acceptable under the relevant code or specification, while a flaw is always considered unacceptable. Because some discontinuities pass inspection while others do not, the two concepts are related but not identical. Inspectors classify discontinuities as acceptable or unacceptable (flaws) based on size, shape, location, and the governing code criteria.
