Electron Beam Welding

The machine consists of two parts. The chamber where the component is manipulated and the gun where the welding beam is generated. Both parts are evacuated to a high vacuum 10-3 to 10-5 mbar. The electron beam is generated by passing current through a filament, applying a high voltage typically 40kv to 150kv and a control voltage to regulate the electron flow (beam current). The resulting beam can be focussed and deflected electrically onto the component joint. The component is manipulated under the beam and a rapid melt and resolidification process occurs which enables deep penetration to be achieved while minimally affecting the state of the surrounding material.
