Electron Beam Welding Process

Strong electric fields which can accelerate electrons to a very high speed.

Electron beam welding process.

The pd in watts per unit area is obtained by the following equation. However when welding at a max. Penetration depth of 3 to 5 mm gaps of up to 0 1 mm are generally allowed. The power density pd defines the process s ability to develop enough heat for welding.

Electron beam welding is used to melt and join base materials. Working of electron beam welding process in electron beam welding the electron is produced by the cathode of the electron gun. The anode which is positively charged attracts the. The electron beam eb welding process is used in a variety of industries.

Electron beam welding provides excellent welding conditions because it involves. The beam of electrons creates kinetic heat as it impacts with the workpieces causing them to melt and bond together. 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.

Using magnetic lenses by which the beam can be shaped into a narrow cone and focused to a very. Because of the high voltage applied across the cathode and anode. 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 process develops energy by bombarding the work piece with a focused beam of high velocity electrons. Because the welding is characterized by a small spot with minimal heat effects couplings with no gaps are ideal. This high speed stream of electrons is tightly focused using magnetic fields and applied to the materials to be joined. 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.
