The Application of Electron Beam Welding on Vacuum Electron Devices

Electron beam welding is widely used in the field of Vacuum Electron Devices (VED). Oxygen free copper (OFC) was welded by electron beam welding with appropriate process parameters for the application of VED. The effects of welding speed and current parameter on welding depth have been studied in the experiment. Microstructure properties of OFC welding were compared with base material. The results show that the welding joint has no apparent surface defects. The welding joint has good performance, and weld penetration has increased with increasing the welding current.
