1

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

2

What are the applications of TIG welding

High quality welds in aluminium and stainless steel

Air craft construction
