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.
The stream of electrons then pass through a hole in the anode.
These electrons are accelerated by applying high potential difference 30 kv to 175 kv between cathode and anode.
Electron beam welding process is carried out in vacuum.
The workpieces melt and flow together as the kinetic energy of the electrons is transformed into heat upon impact.
In this process electrons are emitted from the heated filament called electrode.
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.
The beam is directed by magnetic forces of focusing and deflecting coils.
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.
Ebw is often performed under vacuum conditions to prevent dissipation of the electron beam.
The work piece melt 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.
The electron beam gun has a tungsten filament which is heated freeing electrons.
In this process electrons are emitted from the heated filament called electrode.
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.
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.

A seminar report on beam welding.
The higher the potential difference the higher would be the acceleration of the electrons.
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.
