Welding procedure certification (WPQR)
Where appropriate, the specifications of welding and brazing procedures should be used, increasing the chances of consistently high quality. Welding and brazing procedure specifications should be based on approved procedure certification protocols (WPQR). Adherence to welding and brazing specifications based on approved procedure certification protocols (WPQR) ensures the quality of connections as required.
High requirements are set for the quality of welding and brazing in the production of various products. To ensure this, welders and brazing must strictly adhere to the welding and brazing parameters (method, current, voltage, materials, speed, etc.) specified in the specification of welding and brazing procedures. Welding and brazing procedure specifications are developed by the company itself, but are based on the Welding Procedure Qualification Protocol (WPQR) approved by an independent third party.
Adherence to the Approved Procedure Certification Protocol (WPQR) ensures the quality of the welding and brazing process.
