Quality welds result in increased strength and durability. MIG (Metal Inert Gas) and TIG (Tungsten Inert Gas) welding both use an inert gas to shield the welding process from oxidation and other contamination. MIG uses a continuously feeding wire which serves as electrode and filler/weld material. Generally, MIG is the preferred method for welding thin sheet and some machined products. TIG uses a tungsten electrode, with a separate filler/weld rod. Both methods yield strong, clean and precise welds. TIG is widely used in the aerospace industry and is often used for joining tubing, welding tools and where a corrosion resistant weld is required.
