What is determined with a WPQ?

• A. Welder's skill and ability to deliver sound weld metal
• B. The maximum welding current
• C. The material's mechanical properties
• D. The welding procedure approval number

Answer: (A)

Welder performance qualification focuses on whether a person can consistently deposit sound welds using the specified process. The test checks the welder’s ability to control technique, heat input, travel speed, joint fit-up, and filler metal so the welds meet the required acceptance criteria on the test piece. A successful WPQ shows the welder can reproduce acceptable welds when following the approved procedure, demonstrating skill and competence. It doesn’t determine the maximum welding current, which is set by equipment and process parameters; it doesn’t change the material’s mechanical properties, which come from the base metal and heat treatment; and it isn’t about the procedure’s approval number—the latter relates to the procedure itself, not the welder’s abilities.
