What does WPQ stand for and what is its role in welder certification?

• A. Welding Process Quality; used to verify weld quality.
• B. Welders' Personal Quarters; not related.
• C. Work Procedure Qualification; used to train staff.
• D. Welding Procedure Qualification record; documents the qualification tests for a welding procedure and welder; used to justify WPS.

Answer: (D)

WPQ stands for Welding Procedure Qualification Record. It is the formal documentation of the tests used to prove that a specific welding procedure can produce sound welds under defined conditions (materials, thickness, process, joint design, preheat, interpass temperatures, etc.). The record details exactly what procedure was tested, the test coupons and methods used (tensile, bend, impact, etc.), and the results, showing whether the welds met the required acceptance criteria. Because these results demonstrate that the welding procedure itself is capable, the WPQ is used to justify the Welding Procedure Specification—meaning it provides the proof that the procedure has been qualified and can be used to weld to code. This qualification is a key part of welder certification, since welders are qualified to weld per a procedure only after that procedure has been proven valid in the WPQ.
