How exactly does TIG welding work?

Without getting too technical, a TIG electrode is made from tungsten, and how it works is by simply melting metal together without making use of a filler. The tungsten electrode then gets shielded by a gas nozzle to use shielding gas more effectively. Argon is generally used as the shielding gas, however, sometimes helium is also used as the shielding gas. This gas displaces oxygen and some other elements in order to produce better quality welds.

In some ways, TIG is similar to MIG, however, the latter makes use of a filler via a wire spool which activates when the pedal or trigger is pushed. This spool is then driven by a small motor. Both MIG and TIG make use of shielding gas and a protective nozzle in order to cover the welding tip. ARC (stick) welding will use material within the rod combined with the flux so that it can make more quality welds.

Generally, MIG is easier to learn over both TIG and ARC. TIG if often seen as the hardest of the three to learn. TIG is superior when it comes to using small welds in small spots, for welding the thinner metal and it is also one of the welding types that is used in sanitation welding.

TIG is perfect for sanitation welding as it simply melts the metal together, it completely avoids contaminationg sensitive food processing equipment and lines with contamination from the ARC which is extremely common with MIG and ARC. It is also better for welding some soft metals like aluminium as well.
