In welding procedure qualification, which of the following is most accurate?

• A. PQR stands for Procedure Quality Report; WPS stands for Welding Process Specification.
• B. PQR stands for Process Quality Record; WPS stands for Welding Procedure Standard.
• C. PQR stands for Procedure Qualification Record; WPS stands for Welding Procedure Specification.
• D. PQR stands for Product Quality Review; WPS stands for Welding Procedure Summary.

Answer: (C)

The main idea is the standard terminology used in welding procedure qualification. A Welding Procedure Specification is the written document that tells you exactly how to make the weld—what process to use, materials, positions, welding variables, preheat/post-heat, shielding, and other essential details. A Procedure Qualification Record is the official record of the tests and results that prove that the proposed procedure (the WPS) can produce welds that meet the required standards. It details the test setup, materials, variables, and the acceptance criteria and results.

The correct pairing is that PQR stands for Procedure Qualification Record and WPS stands for Welding Procedure Specification. The other options mix up terms that aren’t standard in this context, such as Procedure Quality Report, Process Quality Record, Welding Procedure Standard, Product Quality Review, or Welding Procedure Summary.
