What is the specification of the welding procedure?

Welding specification (WPS) is the outline of specific welding procedures and techniques that can be used with specific metals and metal alloys. Using a sheet of specification of the welding procedure, a properly trained welder can replicate the same results each time. The specification of the welding procedure is determined by means of a test weld, which is recorded in the qualification record (PQR). The use of these specifications is entrusted with several main industrial organizations. It is used to outline what welding procedures can be used to create safe and durable welds with the material. This outline ensures the safety of consumers and the uniformity of building and manufacturing codes. Before employing, welders must be tested to understand the specifications of the metal welding and processes to work with, and this test is recorded by the welder qualification (WQTR).

different informationFor a given type of metal and the welding process that can be used with metal, it is included in the specification of the welding procedure. In the most basic form, the specification sheet provides the procedure number and the type of test weld process, followed by the relevant information needed to duplicate the test result. The description also includes additional information, such as thickness and welded metal, welding procedures and processes used for test welds, fuel types or electric current used in the welding process, use or lack of preheating, usable welding codes and other variables. In cases where the weld is critical to the structure, more detailed specifications - such as the order of joint assembly, the required heat treatment and the limits of the arc energy - prov.ided to ensure the formation of a solid weld.

6 The production sequence may also be included if an integral part of the welding is performed. Compliance with all this information should be any competent welder capable of reachingNOCE SEPERFUL EFFECTS as a test welder.

Specification of welding procedure records the best welding practice for a given metal or alloy, but does not cover non -destructive testing. Separate non -destructive test processes are required. This non -destructive test procedure is also recorded, but is generally not included in the specification of the welding procedure.
