Carbon arc welding

It was the first arc-welding process developed but is not used for many applications today, having been replaced by twin-carbon-arc welding and other variations.

The purpose of arc welding is to form a bond between separate metal pieces.

CAW could not have been created if not for the discovery of the electric arc by Humphry Davy in 1800, later repeated independently by a Russian physicist Vasily Vladimirovich Petrov in 1802.

Petrov studied the electric arc and proposed its possible uses, including welding.

The inventors of carbon-arc welding were Nikolay Benardos and Stanisław Olszewski, who developed this method in 1881 and patented it later under the name Elektrogefest ("Electric Hephaestus").
