Other welding processes

Welding processes may be classified based on the source of energy they use. The diagram shows main welding processes used in industry.

Welding processes, which use electric arc a source of energy, are most widely used nowadays. These include:

Arc welding with a consumable electrode in shielding gas. International abbreviation for this welding process is either MIG (Metal-Inert-Gas) or MAG (Metal-Active-Gas) depending on the type of shielding gas.

Arc welding with a non-consumable electrode in shielding gas. International abbreviation for this welding process is TIG. The first letter in the abbreviation stands for the material of the electrode, i.e. tungsten (Tungsten-Inert-Gas).
