Summary:Recently, the electron beam welders with high acceleration voltage (more than 100kV) and high electrical power (more than 15kW) has been reviewed the role of the high energy electron beam density again, due to space or aircraft development or automobile industry desired high productivity and high accurate welding for save energy. NEC group have supplied these electron beam welders. This time, the automatic alignment adjustment system of the electron beam orbit, and the automatic adjustment system of filament current, were developed and put to a practical use. As a result, the great effectiveness for stability of welding quality was apparent.
