TIG (tungsten inert gas) welding is a form of arc welding often used on non – ferrous metals and allows for greater control over the weld than other forms of arc welding, which leads to higher quality welds.
TIG welding uses a shielding gas to protect the weld area from defects and embrittlement. This is usually in inert gas.
It's used for a variety of sometimes vastly different applications, from building space vehicles to bicycles. TIG welds are usually very resistant to corrosion, as well as cracking.
Why do we need TIG welders?
TIG welders are vital for creating high quality and strong welds on non-ferrous metal. The greater control compared to other types of arc welding allows for far better welds compared to those forms.
Also, used with orbital and seam welding processes.
Welding together thick sections of stainless steel or non-ferrous metals is the most common use for this method. It is also an arc-welding process that uses a tungsten electrode to produce the weld. The TIG welding process is much more time-consuming than MIG or Stick welding and much more complex. If using a welder with AC/DC you can also weld Aluminium
TIG welding needs a lot more skill and time…

While the aerospace industry is one of the primary users of gas tungsten arc welding, the process is used in a number of other areas. Many industries use GTAW for welding thin workpieces, especially nonferrous metals. It is used extensively in the manufacture of space vehicles, and is also frequently employed to weld small-diameter, thin-wall tubing such as those used in the bicycle industry. In addition, GTAW is often used to make root or first pass welds for piping of various sizes. In maintenance and repair work, the process is commonly used to repair tools and dies, especially components made of aluminum and magnesium. Because the weld metal is not transferred directly across the electric arc like most open arc welding processes, a vast assortment of welding filler metal is available to the welding engineer. In fact, no other welding process permits the welding of so many alloys in so many product configurations. Filler metal alloys, such as elemental aluminum and chromium, can be lost through the electric arc from volatilization. This loss does not occur with the GTAW process. Because the resulting welds have the same chemical integrity as the original base metal or match the base metals more closely, GTAW welds are highly resistant to corrosion and cracking over long time periods, GTAW is the welding procedure of choice for critical welding operations like sealing spent nuclear fuel canisters before burial.
