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 ppt.
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.
The electron beam gun has a tungsten filament which is heated freeing electrons.
The laser beams are focused to the cavity between the two metal pieces to be joined.
Laser beam welding is a fusion welding process in which two metal pieces are joined together by the use of laser.
In this process electrons are emitted from the heated filament called electrode.

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.
In general electron beam welding process is carried out in vacuum.
How do you make an electron beam source.
The stream of electrons then pass through a hole in the anode.
The electrons are accelerated from the source with high voltage potential between a cathode and anode.
The work piece melt as the kinetic energy of the electrons is transformed into heat upon impact.
Electron beam welding ebw is a well established joining method in the field of manufacturing.
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.
In this process electrons are emitted from the heated filament called electrode.
The workpieces melt and flow together as the kinetic energy of the electrons is transformed into heat upon impact.
A stream of electrons is given off from a tungsten filament heated to about 2200 c.
If this technology is downscaled to a micro level i e micro ebw µ ebw it will be able to.
These electrons are accelerated by applying high potential difference 30 kv to 175 kv between cathode and anode.
