Which document contains the tests and results used to qualify a welding procedure?

• A. Welding Procedure Specification
• B. Welder Performance Qualification test record
• C. Post-weld inspection report
• D. Procedure Qualification Record (PQR)

Answer: (D)

The main idea here is understanding which document captures the actual tests and results that prove a welding procedure works. The record that contains the tests performed, the materials and conditions used, and the measured outcomes is the Procedure Qualification Record. This document shows that a specific welding procedure has been evaluated and passed the required tests (like weld coupons and their mechanical or nondestructive test results) under defined conditions, demonstrating that the procedure is capable of producing acceptable welds.

Welding Procedure Specification describes how to perform the weld—the process, filler, materials, positions, and parameters—but it does not include test results. Welder Performance Qualification test records document a welder’s ability to weld to a WPS, focusing on the welder rather than the procedure itself. Post-weld inspection reports record the results of inspections on welded joints after fabrication, not the qualification of the procedure.
