Gas Shielded Arc Welding (GMAW), commonly known as MIG welding, is a welding process that uses a continuous wire electrode and a shielding gas to protect the weld from contamination. The process involves feeding the wire through a welding gun, where an electric arc forms between the wire and the workpiece, melting both to create a strong bond. The shielding gas, often argon or a mixture of argon and carbon dioxide, surrounds the weld area to prevent oxidation and other atmospheric interference. This method is popular in various industries due to its speed, versatility, and ability to weld thin materials effectively.
