There are four main types of welding.

  • MIG – Gas Metal Arc Welding (GMAW),
  • TIG – Gas Tungsten Arc Welding (GTAW),
  • Stick – Shielded Metal Arc Welding (SMAW) and
  • Flux-cored – Flux-cored Arc Welding (FCAW).

Tig Welding 

TIG welding, from time to time is known as Gas Tungsten Arc Welding (GTAW) is the system of the use of electric powered arc with a TIG electrode manufactured from tungsten which do now no longer dissolve or burn off while welding. When TIG welding you're without a doubt melting metall collectively with out the use of a filler metallic as you do with MIG welding.The most important applications for TIG welding are pipeline and pipe welding. It is, however, used in many industries, such as aviation and aerospace and sheet metal industries when welding particularly thin materials and special materials such as titanium.
TIG welding tends to be highly controllable and produces a stable electric arc and a clean, precise, and strong weld. In contrast, in arc or stick welding, the electrode is consumable. Unlike in TIG welding, the electrode acts as the filler metal rod and melts to form part of the weld joint itself. In order to use TiG welding it is important to get the right gas for your weld. The gas that is used for TIG welding is argon. In TIG welding process the arc is formed between a pointed tungsten electrode and the workpiece in an inert atmosphere of argon or helium. 

What materials can you weld with TIG?

TIG welding is suitable for all types of carbon steels, low-alloy steels, alloyed stainless, nickel alloys, aluminum and its alloys, copper and its alloys, titanium, magnesium, and other nonferrous alloys. The use of an infusible electrode makes TIG welding particularly suited for metals only a few millimeters thick.
