Tig stands for tungsten inert welding and in a more technical sense it s known as gas tungsten arc welding gtaw.
Tungsten rod for tig welding.
Gas tungsten arc welding gtaw also known as tungsten inert gas tig welding is an arc welding process that uses a non consumable tungsten electrode to produce the weld the weld area and electrode is protected from oxidation or other atmospheric contamination by an inert shielding gas argon or helium and a filler metal is normally used though some welds known as autogenous welds or.
In addition tip preparation is critical.
The tungsten electrodes can be alloyed with a variety of metals.
There are various tungsten electrodes that you can use for the process but not all will.

The end preparations are balled pointed and truncated.
Choosing one of the six commonly available tungsten electrodes is a crucial first step in successful gas tungsten arc welding gtaw.
The process utilizes a non consumable tungsten electrode that relays current to the welding arc.
Since the composition of the filler rod is the same as mig the same products are sold for tig welding under.
A welder s choice of diameter ranges from 1 16 to 1 4.
The electrode choices are pure tungsten 2 percent thoriated 2 percent ceriated 1 5 percent lanthanated zirconiated and rare earth.
Tungsten inert gas tig welding is a popular type of welding that utilizes tungsten electrodes to join various metals.
