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

  1. A CWI is reviewing a WPS and notices the interpass temperature is not listed. What should the inspector do?

    Answer: Verify whether the applicable code requires interpass temperature on the WPS

    The inspector must verify whether the governing code requires interpass temperature to be listed on the WPS before accepting or rejecting it.

  2. Under AWS D1.1, how long is a welder's qualification valid if the welder has not used the process for more than 6 months?

    Answer: The qualification expires and must be renewed

    AWS D1.1 requires that a welder's qualification expires if the welder has not used the specific welding process for a period exceeding 6 months.

  3. Which of the following is classified as a non-essential variable in a welding procedure under ASME Section IX for SMAW?

    Answer: A change in the weld groove design

    Changes in groove design (such as from V-groove to U-groove) are non-essential variables and do not require requalification of the welding procedure.

  4. When qualifying a welder under AWS D1.1 using a groove weld test in the 2G position, which positions is the welder qualified to weld in production?

    Answer: 1G and 2G

    Under AWS D1.1, a welder who qualifies in the 2G position is qualified for production welding in the 1G and 2G positions.

  5. The heat input formula for a welding process is expressed as:

    Answer: (Amps × Volts × 60) / Travel Speed

    Heat input = (Amps × Volts × 60) / Travel Speed (in inches per minute), giving a result in joules per inch.

  6. A WPS lists a preheat temperature of 200°F minimum. The CWI measures the base metal at 175°F just before welding begins. What action should the inspector take?

    Answer: Stop welding and require additional preheating to meet the 200°F minimum

    The WPS minimum preheat of 200°F is a mandatory requirement; welding must not begin until the base metal reaches at least that temperature.

  7. Which organization publishes the standard qualification requirements for welding procedures and welders used in pressure vessel fabrication?

    Answer: ASME (American Society of Mechanical Engineers)

    ASME Section IX of the Boiler and Pressure Vessel Code governs welding procedure and welder qualification for pressure-containing equipment.
