Which document describes the exact welding parameters used in a production weld?

• A. Welding Processes Specifications
• B. Welding Procedure Specifications
• C. Working Procedure Specifications
• D. Working Shielding Processes

Answer: (B)

The main idea here is how production welds are made consistently. The Welding Procedure Specification is the document that lays out the exact welding parameters for a given joint and material—process, base metal, thickness, filler metal, shielding gas, preheat and interpass temperature, welding position, amperage, voltage, travel speed, technique, and any post-weld heat treatment. This specification is approved to ensure every weld of that type is produced the same way, guaranteeing repeatable quality. While other documents might cover allowed processes or general shop procedures, they don’t specify the exact numbers used in production. That specificity is what makes the Welding Procedure Specification the correct choice.
