Brief introduction to welding procedure qualification record (WPQR) is the test process and result evaluation for verifying the correctness of the proposed welding procedure or for welder capability assessment.            Purpose of welding procedure qualification:            1. Evaluate whether the welding unit has the ability to weld the welded joints that meet the requirements of relevant national or industrial standards and technical specifications.            2. Verify whether the welding process instruction prepared by the welding unit is correct.            3. Provide reliable technical basis for formulating formal welding process instruction or welding process card. 4. Check the welder's ability.            Application scope of welding procedure qualification:            1. It is applicable to the manufacturing, installation and maintenance of steel equipment such as boilers, pressure vessels, pressure pipes, bridges, ships, aerospace, nuclear energy and load-bearing steel structures.            2. Suitable for gas welding, electrode arc welding, tungsten argon arc welding, gas metal arc welding, submerged arc welding, plasma arc welding, electroslag welding and other welding methods.
