What is the primary purpose of a Procedure Qualification Record (PQR)?

• A. It provides a record of the welding performed under a WPS and demonstrates that the welding procedure meets prescribed quality standards.
• B. It outlines supplier material properties.
• C. It lists the welder's job duties.
• D. It describes post-weld cleaning requirements.

Answer: (A)

A Procedure Qualification Record is a documented record that proves a welding procedure has been tested and meets the required quality standards. It captures the actual welding performed under a specific Welding Procedure Specification, along with the test results and conditions (materials, joint design, thickness, process, preheat, heat input, and other parameters). The purpose is to show that, under defined conditions, the procedure can consistently produce sound welds, which then validates the procedure for production use. This record also provides traceability, so the same WPS can be relied upon for ongoing fabrication. Materials properties, welder duties, or post-weld cleaning requirements on their own are not what the PQR is intended to document.
