This section has information on PQRs or Performance Qualification Records (AKA Coupon, Test, Proof Test).

PQRs can be thought of as "what was done" at the company level in terms of welding.  They are welded on "test coupons" (physical components joined together made of plate or pipe) that are typically destructively tested to assure compliance with a given specification/Code. A "Bend Test" where the coupon is bent in a given direction to assure any failure of the coupon occurs above a given value and in a given portion of the coupon (e.g. above the base metals tensile strength with the failure in the base metal not the weld metal).  PQRs are used as "building blocks" or "source material" to construct WPSs that are then use for production welds by qualified and current (i.e., non-expired) welders.PQRs are preformed by Welders/Weld Operators so a WPQ and a PQR would typically both exist in ProWrite for a given coupon.

In ProWrite S9 a single PQR can be used to make one to n WPSs and multiple PQRs can be combined to create a WPS (increasing thickness ranges on the WPS for example). From one to three CEI Processes are supported on a PQR with a "CEI Process" being a combination of process value (e.g. GTAW, GMAW, etc.) and process variables (e.g., Filler Metal, Shielding Gas, Bead Type, etc.). A PQR with multiple Processes can be used to create a single Process WPS or Processes from multiple PQRs can be selectively combined to create a single WPS. In ProWrite D1.1 WPSs can be made from PQRs or as stand alone Pre-Qualified or qualified by Code documents.
