Electron Beam Welding Process

The anode which is positively charged attracts the.

Electron beam welding process.

Strong electric fields which can accelerate electrons to a very high speed. Electron beam welding provides excellent welding conditions because it involves. However when welding at a max. Applications range from fully automated high productivity and low cost automotive in line part production to single part batch processes in the high cost aircraft engine industry at the other end of the industrial spectrum.

Deeper penetrations allow for a larger gap threshold. Working of electron beam welding process in electron beam welding the electron is produced by the cathode of the electron gun. The process develops energy by bombarding the work piece with a focused beam of high velocity electrons. In electron beam welding the kinetic energy of the electrons is converted into heat as they strike the workpiece.

The electron beam eb welding process is used in a variety of industries. The pd in watts per unit area is obtained by the following equation. Thus the electron beam can carry high. 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.

Because of the high voltage applied across the cathode and anode. Electron beam welding ebw is another focused beam welding process. Penetration depth of 3 to 5 mm gaps of up to 0 1 mm are generally allowed. Electron beam eb welding is a fusion welding process whereby electrons are generated by an electron gun and accelerated to high speeds using electrical fields.

This high speed stream of electrons is tightly focused using magnetic fields and applied to the materials to be joined. After cathode a cup grid is. The power density pd defines the process s ability to develop enough heat for welding. Using magnetic lenses by which the beam can be shaped into a narrow cone and focused to a very.
