is the foundational document governing welding, brazing, and fusing procedures and personnel qualifications. It is used to ensure that a welder or welding operator is capable of producing a sound weld and that the welding procedure itself will result in a weld that meets the required mechanical properties. welding standard asme

The PQR is the historical record that serves as the foundation for the WPS. It is created when a test coupon is welded under a specific set of carefully controlled conditions, recording all the actual welding parameters and variables used. After welding, the test coupon is subjected to destructive testing, such as tensile and bend tests, which verify the mechanical properties of the weld. Once this data is recorded and the tests are passed, a WPS can be written based on the proven ranges established in the PQR. ASME updates Section IX every two years
Focuses on testing the manual dexterity of the welder or welding operator.
