Prequalified Welding Procedures (WPS) in Shopfloor
Welding procedure specifications (WPS’s) provide detailed instructions to welders making quality controlled welds. Structural steel welds per AWS D1.1 may be qualified by procedure qualification records, testing or by following the prequalified welding procedures given in AWS D1.1 These WPS qualifications demonstrate that the welding procedure can produce joints that have the required mechanical properties for the intended application.
A prequalified WPS has a specific range of parameters for which preparation of a procedure qualification record (PQR) is not needed. This saves time helping you to working smarter, not harder.
