MIGhitsaus

MIGhitsaus, also known as Gas Metal Arc Welding (GMAW), is a welding process that uses a continuously fed consumable wire electrode and a shielding gas to protect the weld pool from atmospheric contamination. The acronym MIG stands for Metal Inert Gas, though the process can also utilize active gases, hence the broader term GMAW.

In MIG welding, an electric arc is generated between the wire electrode and the workpiece. This arc melts both the electrode and the base metal, creating a molten weld pool that solidifies to form a strong joint. The wire electrode is fed automatically from a spool through a welding gun, which also delivers the shielding gas. Common shielding gases include argon, helium, and carbon dioxide, or mixtures thereof, chosen based on the type of metal being welded and the desired weld characteristics.

The MIG welding process is known for its high deposition rates and relatively easy learning curve, making it popular for both industrial applications and hobbyist use. It can be used to weld a variety of metals, including steel, stainless steel, aluminum, and copper alloys. The versatility and efficiency of MIG welding contribute to its widespread use in manufacturing, automotive repair, construction, and fabrication. Proper setup of voltage, wire feed speed, and gas flow is crucial for achieving high-quality welds.
