Development
CAW could not have been created if not for the discovery of the electric arc by Sir Humphry Davy in 1800, later repeated independently by a Russian physicist Vasily Vladimirovich Petrov in 1802. Petrov studied electric arc and proposed its possible ways of usage, including for welding.
The inventor of carbon-arc welding was another Russian, Nikolay Benardos, who developed this method in 1881 and patented it later under the name Elektrogefest ("Electric Hephaestus").
