Electron beam welding (EBW) is a fusion welding process that joins two materials by using a beam of high-velocity electrons. The electrons produce kinetic energy that is transformed into heat upon impact, melting the workpieces and connecting them with a fusion weld.
EBW is effective in several different welding situations, but it has the advantage of having a narrow weld zone. The electron beam is generated in a high vacuum. While it can weld in medium or non-vacuum conditions, high vacuum welding will provide maximum purity and high depth to width ratio welds.
