Profile: Cambridge Vacuum Engineering is engaged in the manufacture of electron beam welders and vacuum furnaces. We offer a wide range of 60kV and 150kV electron beam welders. Advantages of electron beam welding include a high power density with very low overall heat input and therefore minimum distortion. Electron beam welded parts require a minimum of post weld machining and heat treatment and unlike other fusion welding processes electron beam requires no shielding gases. We supply replacement hot zones for most makes of vacuum furnaces.
