Read the first 7 WPS, PQR, and Welder Qualification flashcards as text

  1. Under ASME Section IX, what is an F-number used to classify?

    Answer: Filler metals grouped by usability characteristics

    F-numbers in ASME Section IX classify filler metals by their usability characteristics to reduce the number of qualification tests required.

  2. A welder qualified using GTAW process wants to also work using SMAW on the same project. What must occur?

    Answer: The welder must qualify separately using the SMAW process

    Each welding process requires separate welder qualification because the skills required to operate GTAW and SMAW are distinct.

  3. During a procedure qualification test, a transverse tensile specimen fails at 68,000 psi. The base metal minimum specified tensile strength is 70,000 psi. What is the result?

    Answer: The test passes if the fracture occurred in the base metal away from the weld

    Under AWS D1.1, a tensile test that fails below the required minimum but fractures in the base metal may still be acceptable per code provisions.

  4. What does the 'A-number' classify in ASME Section IX?

    Answer: The deposited weld metal analysis (chemical composition)

    A-numbers in ASME Section IX classify deposited weld metal according to its chemical composition for procedure qualification purposes.

  5. A WPS qualified with GTAW root and SMAW fill/cap passes for a carbon steel groove weld. If the contractor wants to use GTAW for all passes, what is required?

    Answer: A new PQR supporting a full GTAW WPS must be qualified

    Using GTAW for all passes constitutes a change in the combination of processes, requiring a new or additional PQR to support the revised WPS.

  6. Under AWS D1.1, which test is used to evaluate a welder's qualification for fillet welds specifically?

    Answer: Macro test (cross-section) and fillet weld break test

    AWS D1.1 uses a fillet weld break test and macro examination (cross-section) to evaluate welder qualification for fillet welds.

  7. Which of the following correctly describes an 'essential variable' in the context of welding procedure qualification?

    Answer: A variable whose change requires requalification of the welding procedure

    An essential variable is one that, when changed beyond allowable limits, requires a new PQR and requalification of the welding procedure.
