Electron Beam Welding Ppt

The stream of electrons then pass through a hole in the anode.

Electron beam welding ppt.

In this process electrons are emitted from the heated filament called electrode. Share embed 13 electron beam welding ppt please copy and paste this embed script to where you want to embed. In general electron beam welding process is carried out in vacuum. In this process electrons are emitted from the heated filament called electrode.

Electron beam welding ebw is a well established joining method in the field of manufacturing. Ebw is often performed under vacuum conditions to prevent dissipation of the electron beam. Laser beam welding is a fusion welding process in which two metal pieces are joined together by the use of laser. Report 13 electron beam welding ppt please fill this form we will try to respond as soon as possible.

These electrons are accelerated by applying high potential difference 30 kv to 175 kv between cathode and anode. If this technology is downscaled to a micro level i e micro ebw µ ebw it will be able to. A stream of electrons is given off from a tungsten filament heated to about 2200 c. The electron beam gun has a tungsten filament which is heated freeing electrons.

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. Electron beam welding process is carried out in vacuum. Electron beam welding is a fusion welding process in which a beam of high velocity electrons is applied to two materials to be joined. These electrons are accelerated by applying high potential difference 30 kv to 175 kv between cathode and anode.

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. The workpieces melt and flow together as the kinetic energy of the electrons is transformed into heat upon impact. A seminar report on beam welding. The laser beams are focused to the cavity between the two metal pieces to be joined.

How do you make an electron beam source. The beam is directed by magnetic forces of focusing and deflecting coils. The electrons are accelerated from the source with high voltage potential between a cathode and anode. 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.
