Welding is often used for metal fabrication work. It is an essential skill that can be applied to a wide variety of work environments. Its usage doesn’t stop at the workshop either, it is also used for plumbing, cooking, construction and more. You can also use it for artistic endeavours, making sculptures and large metal installations. TIG stands for Tungsten Inert Gas. It is a process in which a filler rod is used to create a continuous bead on the surface of the metal. This is most commonly used in heavy construction or engineering projects. The base metal must be protected from oxidation throughout the entire process by shielding it with carbon dioxide or argon gas, provided by an air compressor. This is done through the use of a torch that contains an electrode made of tungsten, which conducts electricity while simultaneously heating up to extremely high temperatures. These two elements create the weld once they’re brought into contact with the surface of the metal, while simultaneously providing protection for the base metal.
