  1. What is the meaning of the flag symbol on a weld symbol's reference line?

    Answer: The weld is to be made in the field (not in the shop)

    A flag (pennant) at the junction of the reference line and arrow indicates a field weld, meaning it is to be performed at the erection site rather than in the fabrication shop.

  2. Which condition describes 'overlap' as a weld discontinuity?

    Answer: Weld metal that has not fused with the base metal but has rolled over the weld toe

    Overlap occurs when weld metal flows beyond the weld toe onto the base metal surface without fusing, creating a notch-like condition at the interface.

  3. A CWI must verify that a filler metal bears an AWS classification label before use. This requirement primarily ensures:

    Answer: The filler metal meets minimum mechanical and chemical composition requirements

    AWS classification testing confirms that the filler metal's deposited weld metal meets specified tensile strength, yield strength, and chemical composition requirements.

  4. What is the typical angle of a 'V-groove' weld joint's included angle as commonly specified?

    Answer: 60° to 75°

    A standard V-groove weld typically uses an included angle of 60° (30° bevel per side), though angles from 60° to 75° are common depending on the applicable code.

  5. Postweld heat treatment (PWHT) is primarily performed to:

    Answer: Relieve residual stresses in the weldment

    PWHT (stress relief) heats the weldment to a specified temperature below the transformation range to reduce residual welding stresses and temper hard HAZ microstructures.

  6. Which of the following is considered a surface discontinuity that can be detected by liquid penetrant testing (PT)?

    Answer: A surface-connected crack at the weld toe

    PT detects only surface-open discontinuities; a crack open to the surface at the weld toe will draw in penetrant and become visible during development.

  7. A welder qualification test is designed to determine:

    Answer: Whether a specific welder has the skill to produce sound welds within qualified limits

    Welder performance qualification (WPQ) tests the individual welder's ability and skill, distinguishing it from procedure qualification which tests the process parameters.
