The developmental situation of space welding technology home and abroad is introduced. Then it’s put forward that the designing scheme and the computer aided design (CAD) method of main focusing system of the domestic space electron beam gun with equal-diameter three-cylinder electrostatic single lens. The parameters calculation of the focusing system is completed through language C utilizing computer programming and a satisfying result is gotten.The result shows that electron beam current disperse focusing is less, and the beam section is less in the deflection magnetic field, the beam spot radius on the workpiece is about 0.6300mm at least, and can meet the requirement of the space welding and cutting.
