Procedure Qualification Record
THE LAST PROCEDURE IN THE 4 LEARNING OUTCOMES
WPS is welding procedure specification while PQR is procedure qualification records is all about welding and denotes design when it comes to WPS and Mechanical testing of the design when it comes to PQR. WPS is the design of welding joint, process of welding, welding position, steel shape and material symmetry, speed of welding, welding electrodes and filler and many more welding parameters while PQR is a complimentary to WPS. PQR will be the one to be tested mechanically and will finally validate if the WPS viable design of welding.
Canadian Standard Association, Standard W59, covers welding requirements for carbon and low-alloy welded steel construction
A Welding Procedure Specification (WPS) is a formal document describing http://www.answers.com/topic/welding procedures. According to the http://www.answers.com/topic/american-welding-society-1 (AWS), a WPS provides in detail the required welding variables for specific application to assure http://www.answers.com/topic/repeatability by properly trained http://www.answers.com/topic/welder and welding operators. The American Society For Mechanical Engineers (ASME) similarly defines Welding Procedure Specification (WPS) as a written document that provides direction to the welder or welding operator for making production welds in accordance with Code requirements.
