Electron Beam Welding Process

The power density pd defines the process s ability to develop enough heat for welding. The beam of electrons creates kinetic heat as it impacts with the workpieces causing them to melt and bond together. However when welding at a max.

Electron beam welding process.

In electron beam welding the kinetic energy of the electrons is converted into heat as they strike the workpiece. Thus the electron beam can carry high. The pd in watts per unit area is obtained by the following equation. The anode which is positively charged attracts the.

Using magnetic lenses by which the beam can be shaped into a narrow cone and focused to a very. Working of electron beam welding process in electron beam welding the electron is produced by the cathode of the electron gun. This high speed stream of electrons is tightly focused using magnetic fields and applied to the materials to be joined. Electron beam welding is used to melt and join base materials.

Electron beam welding ebw is another focused beam welding process. 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. Strong electric fields which can accelerate electrons to a very high speed. The process develops energy by bombarding the work piece with a focused beam of high velocity electrons.

Electron beam welding provides excellent welding conditions because it involves. Because the welding is characterized by a small spot with minimal heat effects couplings with no gaps are ideal. Penetration depth of 3 to 5 mm gaps of up to 0 1 mm are generally allowed. The electron beam eb welding process is used in a variety of industries.

Deeper penetrations allow for a larger gap threshold. 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. 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. Because of the high voltage applied across the cathode and anode.
