Electron-beam welding ( EBW) is a fusion welding process in which a beam of high-velocity electrons is applied to two materials to be joined. The workpieces melt and flow together as the kinetic energy of the electrons is transformed into heat upon impact. EBW is often performed under vacuum conditions to prevent dissipation of the electron beam. Oxidation (the process of metals bonding to the oxygen particles in the atmosphere) occurred during the welding process and made welds porous and brittle. Such welds posed a grave risk to workers.
