Fun facts

Welding was known in ancient times. In the Egyptian pyramids, archaeologists found gold products with tin compounds.

The history of welding originates from the discovery of an electric arc in 1802 by the Russian professor of physics Vasily Petrov.

In 1881, the Russian inventor Nikolay Benardos used an electric arc for steel welding for the first time in history.

The French engineers Edmond Fouché and Charles Picard developed the first oxygen-acetylene welding torch in 1902-1904.

Almost any metal and non-metal can be welded in any environment, including Earth's surface, undersea, and space.
