From Tungsten Electrode to GTAW

GTAW, namely the Gas Tungsten Arc Weld, is one kind of non-MIG welding, also known as tungsten inert gas welding (TIG). It is similar to MIG welding, and their dissimilarity is that the GTAW electrodes are made of tungsten which is tungsten electrode that has high melting point, and can withstand high temperatures. Because it does not melt during welding, so there would be no loss. Protect gas acts as flux, if necessary, the filling bar materials can be used to provide the weld with metal. TIG weld almost can weld all metals, in which includes most of the steel, copper, magnesium alloy, aluminum alloy, and part silver, gold, brass, bronze and titanium. The weldment (sheet or the like) which using this process to weld out having a high quality. The following is the part vocabulary content of what mentioned in this article:

Gas Metal Arc Welding (GMAW) refers to, making use of the arc generated from the welding workpiece and the welding wire as a heat source, thereby welding the metal. It has MAG welding (Metal Active Gas shielded arc welding), MIG welding (Metal Inert Gas arc welding) and CO2 welding.

Protective gas refers to, the gas that protecting the hot metal from the ambient air in the welding process, to protect the metal droplet, puddle and weld area.

Solder flux refers to all the material can be used to reduce the base material and the interfacial tension of the solder, including molten salt, organic, metallic steam and gas activity, i.e., the other substances removed base material and the outer solder.
