WPS further explains the rules and details of the test and how the pieces should be assembled. Simply put, a WPS is like a blueprint for welders to produce the same quality of welded product over and over again. Product Qualification Record is another type of document that also refers to welding.
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.
