What is a PQ? The Performance Qualification is used to validate a complete integrated process (e.g. a packaging line consisting of several pieces of equipment). Performance Qualification Protocols test the performance and critical parameter testing for each individual piece of equipment on an integrated process.
The purpose of the document is to guide welders to the accepted procedures so that repeatable and trusted welding techniques are used. A WPS is developed for each material alloy and for each welding type used.Specific codes and/or engineering societies are often the driving force behind the development of a company's WPS. A WPS is supported by a Procedure Qualification Record (PQR or WPQR).A PQR is a record of a test weld performed and tested (more rigorously) to ensure that the procedure will produce a good weld.he AWS defines welding PQR as a record of welding variables used to produce an acceptable test weldment and the results of tests conducted on the weldment to qualify a Welding Procedure Specification. For steel construction (civil engineering structures) AWS D1.1 is a widely used standard.
