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 All the real time data during welding of test coupon and destructive test report data is compiled into one document known as Procedure qualification record (PQR). After successful preparation of PQR, final WPS is prepared and produced to the authorized welding inspector for final approval. WeldNote - Welding Management Software Use the procedure qualification records (PQRs) that were qualified by third-parties, or make your own with our PQR generator. Use them in projects, or write new welding … WELDING PROCEDURE SPECIFICATION WELDING PROCESS: and SUPPORTING PQR: **APPLICABILITY** ASME: AWS: OTHER: REV. NO.: This WPS shall be used in conjunction with the General Welding Standards (GWS) and Welding Fabrication Procedure (WFP) sections and criteria for joint details, repairs, NDE, inspection etc. Weld Joint Type: Class: See GWS 1-06 and WFP's for joint details Preparation:
What is a PQR and why is it important? - CEI
Welding Procedure Specifications (WPS) This document details the practical application of the Procedure Qualification Record (PQR). It should contain enough information to give direction to the welder and should address all variables associated with the welding process defined in QW250 including non essential and supplementary.
May 17, 2019 · PQR is essentially the ‘actual’ method that is used to create and test the welds to ensure they meet all applicable requirements. The test procedures and final results are documented in the PQR. If the PQR meets the set standards of the welding world, then it will serve as the foundation on which one or more WPSs are drafted.
The PQR documents what occurred during welding of the test coupon and the result of the test coupon. The PQR gives suitability of weld for required mechanical properties e.g. strength and ductility. The tension test indicates the strength and the bend tests indicate ductility. Feb 01, 2018 · However, if you’re looking to get a leg up, then you may want to consider AWS Learning’s “WPS/PQR: Explained” interactive online course. This course was created in response to continued feedback from students and educators, and covers the ins and outs of welding procedure specifications and procedure qualification records. The AWS defines welding PQR as a record of welding variables used to produce an acceptable test weldment and the results of tests conducted on the weldment to qualify a Welding Procedure Specification. For steel construction (civil engineering structures) AWS D1.1 is a widely used standard.

Sep 26, 2017 · Welding Procedure Specification (WPS) : A WPS is a written qualified welding procedure prepared to provide direction for making production welds to code requirements. Procedure Qualification Record (PQR) : A PQR is a record of the welding data used to weld a test coupon.
