Welding Wps Meaning. A Welding Procedure Specification or WPS is a formal written document describing standard welding procedures. Welding Procedure Specification WPS is a written and detailed document for the welding operations.
In principle it is prepared in the same way as the WPSs mentioned above but it may be neccessary to calculate the various welding data in advance to ensure that the requested materials properties in the welded joint and the parent materials will be attained. Both documents are closely related but they are not the same. The new NCPWB Welding Procedure Specification numbering system clearly defines the type of metals to be welded the welding process used and allows for identification of variations in a process.
Including ranges if any under which the welding process must be performed.
A Welding Procedure Specification or WPS is a document that serves as a guide for the effective creation of a weld that meets all applicable code requirements and production standards. PWPS is the preliminary WPS used as a work description for welding of test specimen for welding testing. Welding variables that are critical to making acceptable welds are categorized as essential variables. It explains a prescribed description of the welding process gases and flow rates the joint design and geometry the base materials used welding position including various variables.
