The profession of the welder appeared even earlier. Time of its emergence can be considered as 1802 when the Russian scientist VasilyPetrov opened effect of an electric arch at which between two coal electrodes the high temperature allowing to melt metal was created. Soon this opening found practical application — so there was an electric welding. It is curious that welders very quickly realized the professional community: in the 19th century they organized in St. Petersburg “The Russian association of electric processing of metals”.
