Electron beam welding has been known and used for a long time, yet the recent years have seen increasing advancements in equipment fully utilising this welding method potential. Electron beam welding machines can be both universal and highly specialised, which can translate to significant operating and, first of all, welding costs reduction. Modern electron beam welding devices are provided with control systems and safety features which maximise operator’s anti-radiation protection and enable carrying out technological processes in vacuum conditions.
