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…

New, Used and Refurbished TIG Welders for Sale
 
In stock is a vast range of makes and models of TIG welders, GTAW welders and TIG welding machines.
 
Simple Description of the TIG welding application:
TIG Welding is one type of welding amongst a few choices you have - MIG, Stick, Oxyacetylene, etc.

TIG can be used to weld copper, titanium, even two dissimilar metals, and is handy for making tricky welds (e.g. s-curves, or welds on round things)..

TIG generates heat via an arc of electricity jumping from a (tungsten metal) electrode to the metal surfaces you intend to weld - usually aluminum or steel.

TIG stands for Tungsten Inert Gas, after the tungsten electrode, and the sheath of inert gas (argon or an argon mixture) surrounding it. 
Your TIG is likely to have the right electrode in it already.

For aluminum, the best choice is a pure tungsten rod.

You can alternately choose from any number of tungsten alloys (including thoriated tungsten - which is radioactive!) which are uniquely suited to welding particular alloys of metal.
 
There are some very good videos on YouTube demonstrating how to TIG weld - we have given you a few here to get you started.
  
 
GTAW Welding, TIG welding, AC/DC welders, DC welders
Gas Tungsten Arc Welding (GTAW) is frequently referred to as TIG welding.  TIG welding is a commonly used high quality welding process.  TIG welding has become a popular choice of welding processes when high quality, precision welding is required. 
In TIG welding an arc is formed between a non-consumable tungsten electrode and the metal being welded. Gas is fed through the torch to shield the electrode and molten weld pool.  If filler wire is used, it is added to the weld pool separately. 
 

TIG Welding Benefits
Superior quality welds 
Welds can be made with or without filler metal 
Precise control of welding variables (heat) 
Free of spatter 
Low distortion
 
Shielding Gases
Argon 
Argon + Hydrogen 
Argon/Helium
Helium is generally added to increase heat input (increase welding speed or weld penetration).  Hydrogen will result in cleaner looking welds and also increase heat input, however, Hydrogen may promote porosity or hydrogen cracking.

GTAW Welding Limitations
Requires greater welder dexterity than MIG or stick welding 
Lower deposition rates 
More costly for welding thick sections

Applications

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.

 
To find out more technical understanding of TIG welding… or Aluminium welding… we suggest you go to some of the forums online or dedicate welding and joining web sites available.
