Electron Beam Welding Working Principle

In electron beam welding the kinetic energy of the electrons is converted into heat as they strike the workpiece.

Electron beam welding working principle.

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. Ebw is often performed under vacuum conditions to prevent dissipation of the electron beam. Electron beam welding ebw is one another form of the fusion welding process or power beam processes in which the melting and joining of metals is done by heating them with an high velocity electron beam. This heat is further used to weld two welding plates.

The intensity of heat produced is so much that it melts the two metal pieces and fuse them together to form a strong weld. Electron beam welding in vacuum utilizes the kinetic energy of electrons traveling with high velocity in a high vacuum 10 3 to 10 5 mm hg. When a high jet of electrons strike at welding plates its kinetic energy converts into heat energy. This welding works on same principle of electron beam machining.

The workpieces melt and flow together as the kinetic energy of the electrons is transformed into heat upon impact. When the electrons strike the surface of the metal they give up the bulk of their energy as heat and this goes to melt the metal. Dmitri kopeliovich electron beam welding is a welding process utilizing a heat generated by a beam of high energy electrons. This process uses kinetic energy of electrons to produce heat.
