It also contains the test results of the tested specimens. Recorded .A Procedure Qualification Record (PQR) is required for qualifying all SAW, GMAW and FCAW electrodes/electrode fluxes and for qualifying all non-prequalified WPS’s. Following are four .
PQR stands for procedure qualification record. If you run the weld test and the welded plates (or pipe sections) meet the acceptance criteria of the applicable code then the exact parameters used for welding are documented . Procedure Qualification Record (PQR), except that ranges are usually permitted on thicknesses, diameters, welding current, materials, joint types etc. If a WPS is used in conjunction with an approved procedure . The thing to remember in this whole hierarchy of welds and documents is that if done correctly through code-required testing, a WPS is based on facts from successful welds. These successful tests are recorded in the .a written welding procedure specification (WPS) and procedure qualification record (PQR). The WPS provides direction to the welder while making production welds to ASME code requirements. The PQR is a record of the welding data and variables used to weld a test coupon and the test results used to qualify the welding procedure.
Two methods Sawyer utilizes to guarantee quality results from our AWS and ASME certified welding department are advanced welding procedure specifications (WPS) and meticulous procedure qualification records (PQR). A WPS and PQR are required documents in the fabrication process when a weld must comply with a certain standard. Procedure qualification record-PQR Procedure qualification record (PQR) is a supporting document of welding procedure specification (WPS), that is used to record all real-time actual welding parameters variables data during the Welding procedure specification (WPS) or welding of test coupon. And after successful completion of laboratory tests, destructive test .

2. The fabricator to document the test on the appropriate PQR form. 3. The third-party inspector to sign and put his CWI stamp on the PQR form. 4. The third-party inspector to witness the machining and testing of coupons at the testing facility (if required by the Engineer or Owner). The fabricator has a variety of options for qualification.This document contains a specimen procedure qualification record (PQR) for welding processes. It lists information such as the welding process type, base and filler metals used, joint details, preheat and position details, techniques used such as stringer or weave, and test results for visual examination, tensile tests, and guided bend tests. The PQR is intended to be used for the CWI .A Procedure Qualification Record (PQR) documents what occurred during the welding of the test coupon and the results obtained from it. The PQR records the essential variables, specific information, and results of the required testing. Additionally, when notch toughness is required for procedure qualification, the applicable supplementary .
This article explains the differences of WPS (Welding Procedure Specifications) and PQR (Procedure Qualification Record)All SWPSs are supported by procedure qualification records (PQRs) which meet the rules of AWS B2.1 and which in addition are intended to meet the rules of the major codes which govern the intended applications such as AWS Structural Codes (D1.1, D1.2, D1.3, etc.), AWS Sheet Metal Welding Code (D9.1), ASME Boiler and Pressure Vessel Code .3.1.2. Fabrication weld procedures are not to be used for casting weld repairs.
