Carbon Arc Welding -
Carbon arc welding may be classified as single electrode arc welding and twin carbon electrode arc welding. It may further be classified depending upon the nature of shielding. Carbon arc welding may be carried out in air or under an inert atmosphere obtained through the use of a flux or an inert gas (i.e., argon, helium, nitrogen etc.).
Definition
Carbon arc welding is an arc welding process wherein coalescence is produced by heating the workpiece with an electric arc struck between a carbon electrode and the workpiece. Welding may be carried out in air or in an inert atmosphere. Filler material mayor may not be used.
In twin carbon arc welding the arc struck between two carbon electrodes produces coalescence. The workpiece does not form a part of the electrical circuit.
