increase in diameter from size tested in PQR is allowed, except that an increase on electrode size of only 1/32 in. (0.8 mm) in SMAW and increase up to 1/16 in. (1.6 mm) in GTAW is acceptable for use in WPS. For GMAW, only same electrode diameter size tested in PQR is allowed in WPS (Table 4.5 AWS D1.1).]

In case you are wondering, a WPS stands for ‘welding procedure specification’ and a PQR is ‘procedure specification record’. A WPS and PQR are mandatory documents when welds need to comply to a standard. Both documents are closely related, but they are not the same. What is a WPQ and why is it important? - CEI Welder Performance Qualifications (WPQ's) can be thought of as "what was done by a specific welder and what that qualifies the welder to" regarding welding. There will typically be at least one WPQ for every PQR. Generally, there will be more WPQ's than any other document type. What is welding procedure specification (wps) 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. How to write a Welding Procedure Specification (WPS

WPS/PQR Explained | American Welding Society Education Online

Guide to understanding Welding Procedure Specification A WPS is a document that describes how welding is to be carried out in production. Its purpose is to aid the planning and quality control of the welding operation. They are recommended for all welding operations and most application codes and standards make them mandatory. What is Procedure Qualification Record (PQR)?

A welding procedure or weld procedure specification (WPS) is a written instruction that specifies materials, consumables and edge preparations for a given joint. It lists the pre- and post-weld operations including heat treatments; machining, grin

A PQR is a record of the actual values taken and recorded during a test weld performed and tested mechanically by a certified laboratory to ensure that the procedure will produce a good sound weld. How to integrate PQR, WPS and WPQ in SIRFULL™ Welding
