This is also classified as a new welding process because it uses electrons kinetic energy to fuse two metal work pieces Electron Beam Welding is a method which uses a focussed stream of high energy electrons generated by a filament and directed to the joint requiring to be welded. The heating is very localised and the bulk of the assembly therefore remains cold and stable. This results in a very narrow weld with a minimal heat affected zone Electron Beam Welding Process is a fusion welding process in which a high-velocity electron beam is used to join two metals together. The high-velocity electron beam when strikes the weld area of two metal pieces and very intense heat is generated which melts the metal and they fuse together to form a strong weld
Electron beam welding must occur in a vacuum because air molecules interfere with the propagation of the electron beam.

Welcome on our website. If you are interested in Electron Beam Welding technology but ignore everything about it, we will explain it through our different headings and we are waiting for your questions and projects Electron beam welding is the bombardment of a metallic surface by a tightly focussed stream of electrons. This results in a very concentrated (approx. 0.1mm dia.) and intense heat source that melts the metal. By aiming the beam at a joint and then moving the joint under the beam a fully homogeneous fusion of the mating surfaces can be achieved. This activity is carried out within a vacuum. Electron beam welding can never be hand-manipulated, even if not realized in vacuum, as there is always strong X-radiation. The relative motion of the beam and the workpiece is most often achieved by rotation or linear travel of the workpiece. In some cases the welding is realized by moving the beam with the help of a computer controlled deflection system. Workpiece manipulators are mostly.
