TIG welding course

TIG welding is an electric arc welding process in which the fusion energy is produced by an electric arc burning between the workpiece and the tungsten electrode.

During the welding process, the electrode, the arc and the weld pool are protected against the damaging effects of the atmospheric air by an inert shielding gas.  By means of a gas nozzle ,the shielding gas is lead to the welding zone where it replaces the atmospheric air.

TIG welding differs from the other arc welding processes by the fact that the electrode is not consumed like the electrodes in other processes such as MIG/MAG and MMA.
