Abstract: Compared with the traditional fuse additive manufacturing technology based on hot cathode electron beam gun, the fuse additive manufacturing technology based on gas discharge electron beam gun of beam coaxial wire has obvious advantages. In order to shorten the technology gap between the advanced fuse additive manufacturing technology of electron beam in the world, a set of gas discharge electron beam gun of beam coaxial wire with independent intellectual property rights has been developed by analyzing the generation mechanism of gas discharge electron beam gun, and optimizing the cathode and anode parameters that affect the beam quality by using simulation technology. The output electron beam of the gas discharge electron beam gun of beam coaxial wire presents an “X” shape, the droplet transfer mode can be adjusted, and the forming efficiency of the fuse additive manufacturing can reach 5.02kg/h.

Key words: electron beam coaxial wire, fuse additive manufacturing, electron beam, EB gun
