A Welding Procedure Specification (WPS) is a formal document describing how welding is to be carried out in production. A Procedure Qualification Record (PQR) is the test evidence that demonstrates the procedure produces welds of the required quality. Together, WPS/PQR qualification means our welding procedures are tested, documented, and meet international standards.
For clients in the oil and gas industry — where weld failures in pipelines and pressure vessels can have serious consequences — WPS/PQR certified welding is not optional. It provides documentary evidence that every weld on your project follows a tested procedure, executed by a qualified welder.
Our WPS/PQR certification gives clients the confidence that Mechanical Studio's welding meets the standards required for BOST, Sentuo Oil, and similar industrial operators.
