Claims

[Scope of utility model registration request]

An intermediate chamber located between an electron gun chamber that generates an electron beam in a high vacuum atmosphere and a welding chamber that welds objects to be welded in a low vacuum atmosphere; an optical telescope for magnifying and visually observing the irradiation point of the electron beam irradiated on the workpiece; an industrial television camera for displaying the image on a television screen; and an axis line of the electron beam disposed in the intermediate chamber. The image from the irradiation point can be selected for the optical system telescope and the industrial television camera. An electron beam welding device comprising: an electron beam welding device;
