MIG Welding

MIG Welding (Metal Inert Gas) is a welding process in which a continuous, consumable wire electrode and a shielding gas are fed through a welding gun. MIG welding is the most common industrial welding process, due to its versatility, speed, and ease of adaptation. MIG welding is often a robotically automated process, particularly in automotive industry. Constant voltage, direct current (DC) power is most commonly used by MIG welders, but constant current systems and alternating current (AC) power can be used, as well. MIG welding is often used to weld steel, aluminum, and other non-ferrous materials. ''see also: TIG Welding''

The Welding Process

Welding is a process that joins multiple pieces of metal together. In welding this is typically done by melting the different pieces of metal and adding a filler material to form a single pool of molten metal. When this molten metal cools and hardens, the result is a single contiguous joint. While a welding joint is not as strong as a contiguous piece of metal, the joint is far stronger than from other joining processes such as soldering. In the past welding was managed through a process known as forge welding, in which blacksmiths joined iron and steel through heating the metals and hammering them (applying pressure, which in addition to heat causes the welding process). Modern welding techniques have advanced substantially and can involve slame, electric arc, lasers, sound waves, and even electron beams. Modern welders are capable of welding completely submerged under water and in the vacuum of space. Further, automated welding processes are now available, including robot welding. Among the numerous modern welding techniques are:

• Arc welding
• Shielded metal arc welding
• Gas metal arc welding
• Submerged arc welding
• Flux-cored arc welding
• Electric resistance welding
• Electroslag welding
• Oxyfuel welding
• Laser beam welding
• Electromagnetic pulse welding
• Friction stir welding
