What does WPS stand for in welding terminology?

WPS stands for Welding Procedure Specification, which is a crucial document in the welding industry. The WPS outlines the necessary details for welding operations, ensuring consistency, quality, and safety in the welds produced. This document specifies the type of welding process to be used, base materials, filler materials, joint design, and the essential parameters such as amperage, voltage, and travel speed.

Having a Welding Procedure Specification is significant because it serves as a guideline for welders to achieve the desired mechanical properties and performance characteristics of the weld. It also plays a vital role in meeting the requirements set forth by various codes and standards, including those outlined in the Structural Welding Code – Steel (D1.1). By using a properly developed WPS, fabricators can also ensure compliance with industry standards and enhance productivity while reducing the risk of errors during the welding process.
