TIG WELDING
Tungsten Inert Gas (TIG) welding is a process of arc welding which uses tungsten electrodes to produce the weld. This type of welding is formally known as gas tungsten arc welding. TIG welding differs from MIG welding because TIG does not use a consumable electrode.
TIG welding is more difficult, but once learned properly is the most versatile and produced the highest quality weld. TIG welding is most often used for thin sections of stainless steel and metal that do not contain iron, such as aluminum, magnesium and copper.

While TIG welding is used exclusively in the aerospace industry, it has also become a popular method in the making and repairing bicycles. It is also often used for first pass welds for pipes and in manufacturing is frequently used to repair tool and dies, especially those made of aluminum and magnesium.
