Electron beam welding is a method of welding by irradiating an electron beam onto the object to be joined. The electron beam is focused and irradiated to the welded area in a vacuum to perform the welding.

Matsusada Precision manufactures and sells power supplies for electron beam sources, high-voltage power supplies for acceleration, and power supplies for focusing electron beams.
