Describe the principles of TIG welding

Arc is formed between a non-consumable tungsten electrode and the metal being welded

fluxing of joint is achieved by the use of an inert gas shielded arc

Argon is used and flows over electrode- preventing oxygen in the air contacting weld joint

high frequency generator provides a path for the welding current through the shielding gas

filler metal is added manually to the front end of the weld pool as its required


What are the applications of TIG welding

High quality welds in aluminium and stainless steel

Air craft construction
