The procedures for creating and testing the sample welds, as well as the final results, are documented on a Procedure Qualification Record, or PQR. A PQR serves as evidence that a given WPS can be used to produce an acceptable weld. See how ProWrite accurately and uniformly creates PQR documents!
Procedure Qualification Record (PQR): What does it mean? A Procedure Qualification Record (PQR) is a document that provides evidence that a welding procedure produces welds that meet predetermined requirements. PQR is a step before the WPS. A Procedure Qualification Record or PQR begins with the development of a preliminary welding procedure specification (pWPS). pWPS outlines the welding ...

Procedure Qualification Record (PQR) is a document that consists of procedures for creating and testing the sample welds, and the final results as well. PQR is a prior step before Welding Procedure Specification (WPS) document. Simply, a procedure qualification record (PQR) is a supporting document for WPS.

Qualified WPS Filler Metal Allowed by PQR: For SMAW process, only same electrode type (change from low hydrogen to non-low hydrogen is not allowed) and same flux-electrode classification for SAW process. Also same (or lower) strength electrode tested in PQR for SMAW, GMAW and FCAW processes.
WPS vs PQR “WPS” (Welding Procedure Specification) and “PQR” (Procedure Qualification Record) are documents that refer to the practice of welding. WPS is a set of welding instructions. It aids in planning and ensuring quality control of the welded product as well as future reproductions of the product. Welding parameters, such as joint design, position, base metals, electrical ...
