Electron Beam Welding Ppt

The higher the potential difference the higher would be the acceleration of the electrons.

Electron beam welding ppt.

Laser beam welding is a fusion welding process in which two metal pieces are joined together by the use of laser. The laser beams are focused to the cavity between the two metal pieces to be joined. Electron beam welding process is carried out in vacuum. These electrons are accelerated by applying high potential difference 30 kv to 175 kv between cathode and anode.

The beam is directed by magnetic forces of focusing and deflecting coils. The electron beam gun has a tungsten filament which is heated freeing electrons. Report 13 electron beam welding ppt please fill this form we will try to respond as soon as possible. Share embed 13 electron beam welding ppt please copy and paste this embed script to where you want to embed.

The work piece melt as the kinetic energy of the electrons is transformed into heat upon impact. Download 13 electron beam welding ppt comments. 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 is a fusion welding process in which a beam of high velocity electrons is applied to two materials to be joined.

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. The workpieces melt and flow together as the kinetic energy of the electrons is transformed into heat upon impact. Electron beam welding is a fusion welding process in which a beam of high velocity electrons is applied to the material to be joined.

The electrons are accelerated from the source with high voltage potential between a cathode and anode. A stream of electrons is given off from a tungsten filament heated to about 2200 c. How do you make an electron beam source. These electrons are accelerated by applying high potential difference 30 kv to 175 kv between cathode and anode.

A seminar report on beam welding. 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. In general electron beam welding process is carried out in vacuum.

If this technology is downscaled to a micro level i e micro ebw µ ebw it will be able to.
