When welders place their torch to the source material or material being worked on, they need to use a filler metal that will melt, to create the weld.

How-to-Tig-Weld

Gas tungsten arc welding (GTAW) also known as tungsten inert gas(TIG) welding, is an arc welding process that uses a non consumable tungsten electrode to produce the weld.

TIG-Welding-Joints

For light materials the square-edge butt joint is the easiest to prepare and can be welded without filler rod. It consists of “butting” two pieces of metal up against one another (no overlapping) and then welding along the seam between them. If the weld is to be made without filler rod, extreme care must be taken to avoid burning through the metal.

Aluminum Welding

Melting point of Aluminum oxide is nearly 1926 ° C. As the aluminum oxide film becomes thicker, it will start absorbing moisture from the air. Moisture is a source of hydrogen which is the cause of porosity in aluminum welds.
