Abstract
Invention relates to welding engineering and can be used for arc one-sided automatic welding of components with reverse formation of the bottom run on the copper backing. Copper backing is executed in the form of a cylindrical beam, on surface of which the longitudinal channels of different sizes and form are executed, on the surface between adjacent grooves is executed a longitudinal slit cut, which communicates with internal screen with a length, which is equal to the length of beam, in which is established a luminous source, and also the housing has a catch of position of beam with selected groove.
