A WPQ typically assesses which aspects of welding?

• A. Only the speed of travel.
• B. Joint quality, weld profile, and mechanical test results per procedure.
• C. Only the color of the weld rim.
• D. Only the noise produced by the welder.

Answer: (B)

Welder Performance Qualification tests whether a welder can produce a weld that meets the welding procedure specification under controlled conditions. It focuses on three things: the joint quality (no defects like cracks, porosity, or lack of fusion), the weld profile (the bead geometry, reinforcement, and overall dimensions within the specified limits), and the mechanical test results required by the procedure (such as tensile and/or bend tests) to prove the weld will meet the intended strength and toughness. Travel speed, color of the weld rim, or noise don’t measure the weld’s integrity or its compliance with the procedure, so they aren’t what this qualification examines.
