Welding & Paint Inspection

Procedure Specifications, WPS, & Material Lab. Testing

In order to qualify WPS and to certify welders, series of destructive mechanical tests should be carried out. These include Tensile Test, Bending test, Impact Test, Hardness Test, and Metallographic test. This is usually followed by a volumetric NDT Test (RT or UT). Accordingly, PQR & WPQR are written based on laboratory results.

Welder Performance Qualification Record, WPQR, & PQR

For any given professional industrial mass welding jobs, all production welders have to be certified to the production WPS by WPQRs. Those are usually governed by several standards like AWS D1.1, ASME IX, API 1104... etc.; This has to be attended & visually inspected by a third party
