Welding Procedure Qualification Records’ (WPQR) Tests and Approval
There are different settings for each type of weld applied, and the properties and quality of the welds change as well. Each customer may request information about the welding applied to their contractor by another controlling company, and that any test results meet any standard. The contractor can call the source the company has applied to the company, inviting the impartial company to where it has its controllers and request tests. As a result, the controlling company provides the PQR (Procedure Qualification Report) and the results of the tests with it, provided that the standards are successfully passed by any standard.
