In TIG (Tungsten Inert Gas) welding, an arc is drawn between a non-consumable tungsten electrode and the work piece. The electrode, the arc and the weld pool are protected from the atmosphere with an inert shielding gas. For manual welding the hardfacing material is in the form of a rod. Advantages of the TIG process include simple manual operation and good control of the welding arc. The process can also be mechanised, in which case a manipulator is used to move the work piece in relation to the welding torch and the hardfacing rod.
Rods are also used for hardfacing with the Oxy Acetylene welding process. With the correct operation, a very low level of iron dilution can be achieved in the overlay.
Benefits of TIG Welding;
• Manual Operation
• Can Be Mechanised
• Low Dilution
