MIG (Metal Inert Gas) Welding is a process in which an electric arc forms between a consumable wire electrode and the workpiece metal, heating them to the point of fusion. Shielding gas, typically a combination of argon and carbon dioxide, is used to protect the weld from atmospheric contamination. SPM stands for Special Purpose Machine, which in the context of welding typically refers to automated or semi-automated welding systems designed for specific applications or high-volume production.
SPM for MIG Welding plays a crucial role in increasing productivity, improving weld quality, and reducing labor costs in various manufacturing industries.
