MIG welding, or Metal Inert Gas welding, is a versatile and widely used welding process ideal for beginners and professionals alike. It uses a continuous wire electrode fed through a welding gun, which melts and joins metals together. A shielding gas, typically argon or a mix of argon and carbon dioxide, protects the weld pool from atmospheric contamination. Known for its speed, efficiency, and ability to produce clean welds, MIG welding is commonly employed in automotive, construction, and manufacturing industries.
