  1. A contractor uses an AWS D1.1 prequalified WPS for a structural steel project. Which statement about prequalified WPSs is correct?

    Answer: They do not require testing if all prequalified conditions are met

    AWS D1.1 prequalified WPSs are exempt from qualification testing provided all conditions listed in the prequalified requirements are strictly met.

  2. Under ASME Section IX, what is the minimum number of bend specimens required for procedure qualification of a groove weld?

    Answer: Two side bend specimens (for material 3/4 inch or thicker)

    For base metal 3/4 inch or thicker, ASME Section IX requires two side-bend test specimens; thinner material uses face and root bends instead.

  3. A welder's qualification record shows qualification with E7018 (F4) electrodes. Can this welder also use E6013 (F3) electrodes without requalification under ASME Section IX?

    Answer: Yes, because qualification with a higher F-number qualifies for all lower F-numbers in the same base metal P-group

    Under ASME Section IX, welder qualification with a higher F-number filler metal qualifies the welder to use any lower F-number filler metal of the same process.

  4. On a WPS, the term 'PWHT' refers to:

    Answer: Post-Weld Heat Treatment applied after welding is complete

    PWHT (Post-Weld Heat Treatment) is a controlled heating and cooling process applied to the weld after completion to relieve residual stresses and improve properties.

  5. Which of the following changes to a WPS would require a new PQR under AWS D1.1 structural welding?

    Answer: Increasing the interpass temperature above the maximum listed in the WPS

    Exceeding the maximum interpass temperature specified in the WPS/PQR is an essential variable change that may require requalification depending on the code requirements.

  6. A CWI is asked to verify that a welder is qualified for the groove weld position being used in production. Where should the inspector look first?

    Answer: The Welder Qualification Test Record (WQTR) or Performance Qualification Record

    The Welder Qualification Test Record (WQTR) documents the specific positions, processes, and base metals for which a welder is qualified.

  7. Under ASME Section IX, the 'P-number' system is used to group:

    Answer: Base metals with similar weldability and mechanical properties to reduce qualification testing

    ASME Section IX assigns P-numbers to base metals with similar composition, weldability, and mechanical properties to minimize the number of procedure qualifications needed.
