A seminar report on beam welding. Report 13 electron beam welding ppt please fill this form we will try to respond as soon as possible. The stream of electrons then pass through a hole in the anode. Electron beam welding ebw is a well established joining method in the field of manufacturing.

The electron beam gun has a tungsten filament which is heated freeing electrons. The workpieces melt and flow together as the kinetic energy of the electrons is transformed into heat upon impact. The higher the potential difference the higher would be the acceleration of the electrons. The electrons are accelerated from the source with high voltage potential between a cathode and anode.

These electrons are accelerated by applying high potential difference 30 kv to 175 kv between cathode and anode. Ebw is often performed under vacuum conditions to prevent dissipation of the electron beam. Electron beam or laser welding ppt measurement of electron beam polarization at stanford an overview of densification microstructure and mechanical electron beams solved 4 the diagram to right res an old fash. Electron beam welding is a fusion welding process in which a beam of high velocity electrons is applied to the material to be joined.

Electron beam welding is a fusion welding process in which a beam of high velocity electrons is applied to two materials to be joined. Guided by fig 1 1 electron beam welding the electron beam is produced in a high vacuum environment by an electron gun usually consisting of a tungsten or tantalum cathode a grid or forming electrode and a anode. In this process electrons are emitted from the heated filament called electrode. The laser beams are focused to the cavity between the two metal pieces to be joined.

The work piece melt as the kinetic energy of the electrons is transformed into heat upon impact. The beam is directed by magnetic forces of focusing and deflecting coils.

The laser beams have enough energy and when it strikes the metal pieces produce heat that melts the material from the two metal pieces and fills the cavity. Electron beam welding process is carried out in vacuum. In this process electrons are emitted from the heated filament called electrode. These electrons are accelerated by applying high potential difference 30 kv to 175 kv between cathode and anode.

How do you make an electron beam source.
