ELECTRON-BEAM WELDING DEVICE FOR A VACUUM ENCLOSURE

摘要

A SEALING DEVICE FOR A VACUUM ENCLOSURE A vacuum enclosure rests on two parts to be seamwelded by the electron-beam welding technique and surrounds a support for an electron gun. The support is made up of two separable elements, the first element being constituted by a frame applied in vacuum-tight manner against the parts to be welded by means of a seal fitted on one face, the other face being applied against a flange of the second element which forms a bell-housing and is applied against the frame.
