work pieces – and an electrode that is guided along the joint between the pieces. The electrode is either a rod that simply carries current between the tip and thework, or a rod or wire that melts and supplies filler metal to the joint.Different Types of Welding ProcessesMIG - Gas Metal Arc Welding (GMAW)TIG - Gas Tungsten Arc Welding (GTAW)Stick - Shielded Metal Arc Welding (SMAW)Flux-Cored Arc Welding (FCAWMIG - Gas Metal Arc Welding (GMAW)
This welding process uses a continuously fed electrode through a welding gun and the operator needs to pull a trigger in order to feed the consumable electrode through. Between the base material and the electrode an electric arc forms, which heats the material until it reaches the melting point that makes it possible to get it joined with another.For this type of welding, you need an externally supplied shielding gas, and some of the most common used gases for this purpose are stainless steel, carbon steel, magnesium, copper, nickel, aluminum, and silicon bronze. Some of the typical uses for MIG weldingTIG - Gas Tungsten Arc Welding (GTAWAlso known as Heliarc welding, TIG is a welding process that uses a tungsten electrode that is not consumable to heed the base metal and create a molten puddle for the by using this method, you can create are no filler metal or autogenous weld in order to melt two pieces of metal together. You can also add an external filler rod into the molten puddle in order to be able to create a weld bead and increase the mechanical properties of the metal.
