How can you identify the proper welding techniques for a specific material?

Referring to the welding procedure specification (WPS) is essential for identifying the proper welding techniques for a specific material because the WPS provides detailed instructions on how to carry out the welding process for that material. It includes critical information such as the type of welding process to use, the appropriate filler materials, preheat and interpass temperatures, welding positions, and the settings for equipment. This standardized documentation ensures consistency and safety in the welding operation, as it has typically been developed and tested under controlled conditions. Relying on the WPS helps welders adhere to industry standards and best practices, minimizing the risk of defects in the weld and improving overall weld quality.
