ABSTRACT:
An electron beam welding apparatus performs electron welding by irradiating electron beam on a workpiece. At an arcing point where the electron beam is irradiated, welding spatter is generated. The welding spatter can fly in a working chamber and can adhere to a housing of a welding apparatus. For preventing this, a spatter catching means is provided for preventing the welding spatter from directly adhering to the peripheral wall surface of the housing. Preferably, a spatter catching means comprises a cover member surrounding the workpiece so that the area of flying of the welding spatter is limited within the surrounded region.
