Advanced Possibilities of Using Profile Electron Beams Formed by High-Voltage Glow Discharge Electron Guns in Modern Industrial Applications

Advanced possibilities of using profile electron beams, formed by high-voltage glow discharge electron guns, are considered in this paper. Such advanced electron-beam technologies as single-pulse welding, remelting of refractory materials with an intermediate capacity, and 3D printing of the metals have been considered. A corresponding schemes of construction for electron guns as well as technological equipment are also given. Comparing the results of 3D printing using simple point-focus and profile electron beams is also presented.
