摘要：
The metal transfer mode of electron beam welding(EBW) with filler wire was studied experimentally.The spatial position between the electron beam and the filler wire was defined.Basing on the charge coupled device(CCD) visual sensing system,the metal transfer mode of filler wire was investigated.The results showed that there were five transfer modes during EBW process due to different wire feed rates and spatial positions between beam and filler wire,such as short-circuiting mode,molten metal bridge mode,small droplet mode,big droplet mode and mixed mode.By comparing the weld appearance of different transfer modes,the molten metal bridge transfer was proved to be the best transfer mode.
