What is Tig Welding?

Well, to start with, let’s get the proper name here. Gas Tungsten Arc Welding (GTAW) is the proper term for this process nowadays. Tungsten inert gas is what the Tig stands for.

This process is similar to Oxyfuel in how it is applied but its power source is the same as SMAW or stick welding. The torch holds a non-consumable electrode, in this case, Tungsten which allows the current to flow for the arc and in turn creates a molten puddle. Shielding gas is supplied by means of a separate cylinder controlled by a regulator. Filler metal is added manually just like you would if you were Oxyfuel welding.

One of the cool things is the ability to control the current with either a thumb control or a foot pedal. You don’t always have that luxury with stick welding. So what can we do with it?

You can weld basically every form of electrically conductive metal such as:

Steel, stainless, aluminum, nickel, copper, titanium and maybe unobtanium. The process can be time-consuming for some but the results are usually worth the wait. Not to long ago we had to repair a floor panel on a car carrying trailer. It was aluminum and we wanted to make it look as natural as possible. So the obvious choice was to “Tig” it.

The hole was created by large shipment that punctured and tore a hole thru the floor panel. The material was 6xxx series so we chose 5356 filler metal to fill up the hole with just filler metal. Sometimes and often on which the object is to be used will determine how to fill the hole. If we put a piece of aluminum over the hole and welded that to the area it would always be visible and someone could trip over it.

It is not really that hard to do except for possibly getting a leg cramp or a toe cramp because of the position it had to be done in. It is difficult to operate the foot pedal with your knee.

After a few moments of welding, the hole was filled and grinded down smooth with a flap wheel. You had to be in a certain spot to even tell it was there, and that is what I call magic!
