A Welding Procedure Specification (WPS) is the formal written document describing welding procedures, which provides direction to the welder or welding operators for making sound and quality production welds as per the code requirements . 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. Individual welders are certified with a qualification test documented in a Welder Qualification Test Record (WQTR) that shows they have the understanding and demonstrated ability to work within the specified WPS. Welding procedure specifications (WPS) allow welders to consistently produce welds that meet desired requirements without any rework. However, the nature and use of a WPS, and its supporting procedure qualification record (PQR), are commonly misunderstood. This online course provides a comprehensive overview of these documents in an engaging and easy-to-understand multimedia format.

Topics include: the format and function of a WPS and a PQR; the different types of WPSs; essential and nonessential variables for arc welding, oxyfuel welding , resistance welding and brazing procedure specifications; the procedure qualification process; the information included on a PQR; and common nondestructive and destructive tests.

The same basic WPQ may however be copied for multiple welders (allowing many welders to have similar qualification ranges to enable flexibility in management). Each WPQ is associated with just 1 Welder in ProWrite but a WPQ number can be duplicated across WPQ's so every welder in a shop may have their own "WPQ 6".

WPQ can be made from a WPQ Template, a PQR, a WPS or as a stand-alone document. A WPQ in ProWrtie D1.1 can be made from a WPS or as a stand-alone document
