Electron Beam Welding Process

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

Electron beam welding process.

The process develops energy by bombarding the work piece with a focused beam of high velocity electrons. The pd in watts per unit area is obtained by the following equation. The power density pd defines the process s ability to develop enough heat for welding. After cathode a cup grid is.

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 eb welding is a fusion welding process whereby electrons are generated by an electron gun and accelerated to high speeds using electrical fields. Because the welding is characterized by a small spot with minimal heat effects couplings with no gaps are ideal.

The electron beam eb welding process is used in a variety of industries. Thus the electron beam can carry high. However when welding at a max. Working of electron beam welding process in electron beam welding the electron is produced by the cathode of the electron gun.

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. The anode which is positively charged attracts the. Deeper penetrations allow for a larger gap threshold. Electron beam welding provides excellent welding conditions because it involves.

Strong electric fields which can accelerate electrons to a very high speed. Because of the high voltage applied across the cathode and anode. Electron beam welding is used to melt and join base materials. Electron beam welding ebw is another focused beam welding process.
