What does a Procedure Qualification Record (PQR) provide?

• A. It provides a record of the welding that actually took place while following a specific procedure (WPS).
• B. It lists the equipment used in welding.
• C. It certifies the welder's qualifications.
• D. It contains the material chemical composition.

Answer: (A)

A PQR records the welding that was actually done under a specific welding procedure specification to demonstrate that the procedure can produce acceptable welds. It captures the exact conditions used—base and filler materials, joint design, welding position, and the welding parameters—and the results of the required tests (mechanical tests and any non-destructive tests). This document proves that the procedure is capable and can be used to create consistent, code-compliant welds, forming the basis for establishing a WPS. It’s not a list of equipment, it doesn’t certify a welder’s qualifications (that’s a separate WPQ), and while material chemistry may be included, the main purpose is to document the welding performed and the test outcomes that validate the procedure.
