A welding procedure specification (WPS) prepared by the Welding Research Council (WRC) Welding Procedures Committee. The committee uses procedure qualification reports (PQRs) which it develops or those developed by industries and donated. After the standard welding procedure specifications are prepared by the WRC committee, they are sent to the American Welding Society (AWS) B2 Committee on Qualification. The documents then proceed through the AWS ballot sequence, and after approval at all levels, become American National Standards.
