From Specification to Practice

A Welding Procedure Specification (WPS) is a formal document providing the "recipe" for making a code-compliant weld. It lists essential variables, including the allowable range for heat input. The role of a welding supervisor or QC inspector is to ensure that the welder on the floor is actually following that recipe. This tool is designed to bridge the gap between the paper specification and the live welding on the shop floor, providing real-time feedback on whether the current parameters are compliant.
