Electron Beam Welding
Introduction:
⚓️ Electron Beam Welding (EBW) is fusion welding process in which a beam of high velocity electrons is used for producing high temprature and melting the workpiece to be welded. The electrons strikes the workpiece and there Kinetic energy is converted into thermal energy by releasing heat which is used to heat the metal so that the edges of workpiece are fused and joined together forming a weld.

Working principle:
⚓️ If a filament of tungsten or tantalum is heated to high temperature in a vacuum either directly by means of electric current or indirectly by means of an adjacent heater, a great number of electrons are given off from the filament. These electrons carry a negative charge which is passed through the anode hole. The greater is the filament current, the higher will be the temperature and greater will be the electron emission.
