MIG (Metal Inert Gas) welding is a welding process in which an electric arc forms between a consumable wire electrode and the work piece.

TIG welding is a  tungsten electrode heats the metal you are welding and gas (most commonly Argon) protects the weld puddle from airborne contaminants. TIG welding produces clean, precise welds on any metal.

Structural welding is used to create metal frameworks for buildings, bridges, vehicles, and a variety of other complex structures. Structural welding is also used to cut and repair beams, columns, and girders.
