Arc welding power supplies can deliver either direct (DC) or alternating (AC) current to the work, while consumable or non-consumable electrodes are used. The welding area is usually protected by some type of shielding gas (e.g. an inert gas), vapor, or slag. Arc welding processes may be manual, semi-automatic, or fully automated.
During the 1860s and 1870s he investigated the electric arc, and he worked on this in Moscow, St. Petersburg and Kineshma. [1] Nikolay Benardos was the first to apply an electric arc to heat the edges of the steel sheets to the plastic state. [1] He demonstrated a new way of metal compounds in Paris in 1881. [1]

Carbon arc welding (CAW) is an arc welding process which produces coalescence of metals by heating them with an arc between a non-consumable carbon electrode and the work-piece. It was the first arc-welding process developed but is not used for many applications today, having been replaced by twin-carbon-arc welding and other variations.
Locomotive cylinders welded by quasi-arc process at Hillside Engineering in New Zealand on 16 June 1926. The Quasi-Arc Company was a provider of arc welding equipment and consumables. The company was founded around 1911 by William Lawes Cole, Arthur P. Strohmenger and C. H. Champness. Its head office was in Grosvenor Gardens, London.
