industry continued to grow during the following centuries.[3] In 1802‚ Russian scientist Vasily Petrov discovered the electric arc[4] and subsequently proposed its possible practical applications‚ including welding. In 1881–82 a Russian inventor Nikolai Benardos created the first electric arc welding method known as carbon arc welding‚ using carbon electrodes. The advances in arc welding continued with the invention of metal electrodes in the late 1800s by a Russian‚ Nikolai Slavyanov (1888)‚ and an American
