Abstract In order to obtain a high-quality electron beam source, based on the in-depth analysis of the electron beam gun structure, the key parameters affecting the beam quality were simulated and optimized, and a set of medium-voltage long focal distance high-power electron beam gun was designed and manufactured by using the optimized parameters. On the beam source quality test platform, the maximum working distance and maximum welding depth of the developed electron beam gun were tested. The test results show that the working distance of the developed electron beam gun is 200–600mm, the maximum weld depth for welding TC4–DT titanium alloy reaches 60mm, and the weld aspect ratio can reach 10:1.
