This paper reports and analyzes the form and working principle of CNC (Computerized Numerical Control) electron beam welding machine. And it proposes that the electron beam welding machine is controlled by FX2N-80MR PLC (programming Logic Control),and uses computer CNC program to control working table. According to the controlling systems of electron beam welding machine and welding technology requirements, the form and function about hardware and software of electron beam welding machine and CNC program are described in detail in this paper. The run shows that they work reliably and the function is perfect.
