The American Welding Society states that before a Welding Procedure Specification (WPS) can be drafted, a preliminary set of procedures and materials must be established.
This initial procedure is used to create a series of welds, which are then tested to ensure they meet applicable requirements.
The procedures for creating and testing the sample welds, as well as the final results, are documented on a Procedure Qualification Record, or PQR. If the test results are acceptable, the PQR is approved and can then serve as the foundation on which one or more WPS's are drafted.
In short, a PQR serves as evidence that a given WPS can, in fact, be used to produce an acceptable weld.
This short video, presented by Antonio Howard, highlights how ProWrite software supports accurately documenting welding related activities to assure the uniform application of generally accepted safe welding practices in the manufacture and fabrication of boilers & pressure vessels.

Weld Toolbox - CAD is a FREE welding joint and weld symbols utility that utilizes design wizards to help you easily document the types of welds, including the weld symbols you need to give your documents a professional appearance.
This is a stand-alone utility for PC's only that you can use without CAD systems or other engineering software.
