Summary:The course of overlay welding technology qualification using welding procedure test according to the PN-EN ISO 15614-7 specifications is described. How the preliminary welding procedure specification (pWPS) should be prepared is clarified and the type of test pieces as well as the type of tests that should be carried out after overlay welding are presented. The criteria to be met by test pieces so that the welding procedure may be qualified as acceptable are discussed. The qualification range and the details of the welding procedure qualification record (WPQR) also presented. Numerous examples of overlay welding procedure qualification tests, carried out at the Welding Institute are described.
