......Electron Beam Welding is a precision fusion metal joining process. A stream of electrons are focused to a spot on the joint to be welded. When they hit the metal, it melts and fuses together.

......EBW is a fusion joining process that produces coalescence of the metals with heat from a high energy electron beam focused on the weld joint. The kinetic energy of the electrons is changed into heat upon impact with the work piece. The electron beam process must be carried out in a vacuum atmosphere.

.....Electrons are generated by heating the filament located in the electron beam gun. The electrons are then shaped to form the electron beam. The beam travels through an anode/column valve/magnetic focusing lens/deflecting coil, entering the chamber work area to the part where it's accelerated to a velocity of ½ the speed of light.

.....This concentrated stream of electrons generates kinetic energy upon impact with the metal part, creating heat resulting in fusion or melting of the two pieces to be joined.

.....EBW is particularly suitable to any application that requires minimized distortion and shrinkage during welding, welding in a close proximity to heat sensitive components or attachments, or hermetic seal welding of evacuated enclosures while retaining a vacuum inside the component.
