TIG welding obliges three thing, high temperature, protecting, and filler metal. The hotness is created by power going through the tungsten cathode by making a bend to the metal. The protecting originates from a compacted container of gas that streams to the weld region to shield it from air. The filler metal is only a wire that is plunged by hand into the curve and liquefied. The way these three things meet up is really straightforward. First and foremost the welder turns on the gas stream, commonly by a valve on the TIG light itself. The gas starts to stream and begins shielding the weld region from the air. The light is held over the weld joint sufficiently far for the light not to touch the metal. At that point the welder presses a foot pedal and the TIG lights tungsten anode begins a circular segment. When the bend is begun the two bits of metal start to dissolve by making a puddle of metal. When the puddle is built the welder with the other hand begins filling the joint by physically plunging a welding wire into the circular segment to fill the joint. At last this methodology makes a solitary bit of metal.

 

TIG Welding Shielding Gasses

 

Protecting gasses for TIG welding are utilized to shield the weld zone from any air that will debase the weld. The two most usually utilized gasses to TIG weld are:

 

Argon / Ar (typically used)

 

 Helium / He

 

Since Argon and Helium are Nobel dormant gasses they don't change the qualities of the weld joint. What you weld with, is the thing that you get. In some uncommon cases there are three sorts of mixture utilized. The main is Argon and hydrogen and the second is Argon and Nitrogen. The third mixture is Argon and Helium and that is regularly utilized on thicker metals to get deeper weld entrance. By and large immaculate Argon will cover pretty much everything welding needs.
