Electron Beam Welding Process

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.

Electron beam welding process.

The process develops energy by bombarding the work piece with a focused beam of high velocity electrons. Strong electric fields which can accelerate electrons to a very high speed. Thus the electron beam can carry high. Penetration depth of 3 to 5 mm gaps of up to 0 1 mm are generally allowed.

This high speed stream of electrons is tightly focused using magnetic fields and applied to the materials to be joined. The beam of electrons creates kinetic heat as it impacts with the workpieces causing them to melt and bond together. Electron beam welding provides excellent welding conditions because it involves. Electron beam welding ebw is another focused beam welding process.

Working of electron beam welding process in electron beam welding the electron is produced by the cathode of the electron gun. Deeper penetrations allow for a larger gap threshold. In electron beam welding the kinetic energy of the electrons is converted into heat as they strike the workpiece. The anode which is positively charged attracts the.

The pd in watts per unit area is obtained by the following equation. However when welding at a max. 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 welding is used to melt and join base materials.

After cathode a cup grid is. Because of the high voltage applied across the cathode and anode. Because the welding is characterized by a small spot with minimal heat effects couplings with no gaps are ideal. Using magnetic lenses by which the beam can be shaped into a narrow cone and focused to a very.
