A Welding Procedure Specification (WPS) is a formal document describing welding procedures. It is an internal document used by welding companies to instruct welders (or welding operators) on how to achieve quality production welds that meet all relevant code requirements.

This is a list of welding processes, separated into their respective categories. The associated N reference numbers (second column) are specified in ISO 4063 (in the European Union published as EN ISO 4063 ). [ 1 ]
A standard specification is an explicit set of requirements for an item, material, component, system or service. It is often used to formalize the technical aspects of a procurement agreement or contract. [2] For example, there may be a specification for a turbine blade for a jet engine that defines the exact material and performance requirements.
Methods of weld testing and analysis are used to assure the quality and correctness of the weld after it is completed. This term generally refers to testing and analysis focused on the quality and strength of the weld but may refer to technological actions to check for the presence, position, and extent of welds.
The evolution of welding technology has been driven by advancements in Weld quality assurance, welding codes, and standards for welding inspection. [11] While the origins of welding can be traced back to approximately 3000 B.C., the need for effective weld joint inspection became increasingly apparent during the late 19th and early 20th centuries, coinciding with the rise of industrialization ...
In addition to welders and welding machine operators, there are also schemes to independently certify welding inspectors and related specialities. The duties of the welding inspector are described in ISO 14731; [12] however the requirement for inspector certification are not standardized, so there are differences in requirement between the various schemes.
