TIG in TIG welding stands for Tungsten Inert Gas. It is also known as Gas Tungsten Arc Welding (GTAW) and involves the use of non-consumable tungsten electrode to deliver current to the welding arc. This welding technique was developed in 1930s and was used during the times of secong world war to weld parts of aircraft and is today used in welding stainless steel, chromoly, aluminum, bronze, brass and gold.

How to weld with TIG?

Logosweld is among the top welding electrodes machine suppliers inIndia. Here is a brief expalnation on how the TIG weld works.
The first step is to clean the welding material. You can use stainless stell wire brush for aluminum, sander for carbon steel while for stainless steel all you need to do is wipe the weld area with a solvent. Once the surface is clean, the next step is to use tungsten electrode. You need to open the back of the electrode holder on the collet. Then insert the tungsten electrode and close the electrode holder. Make it a point that the electrode hangs at least 1/4-inch away from the protective sheath on the collet.
Now use a C-clamps to secure the parts you wish to weld together. You can also make use of tack welds to hold the parts in place, until the final welding has taken place. The next step is to hold the TIG torch at about 75 degree angle, with the tunsgten raised up to 1/4 inch off the metal. It is important that the tungsten does not touch the work piece, or else it will contaminate the material.
With the torch heatup the base metal and advance the puddle in the desired direction using your arc. Continue to advance the puddle until the whole of the desired area has been welded.
And with this your TIG welding has been completed.
