Electrons are generated by heating the filament located in the electron beam gun (grid). Because of the special design of this gun, the electrons are shaped to form the electron beam. The beam then travels through the following:
![]() |
-> Anode |
The stream of high voltage electrons is accelerated to a velocity of approximately 2/3 (two thirds) the speed of light or about 117,000 miles per second.
The machine operator views the welding operation directly through optics or remotely through a CCTV attachment.
Load part or parts in a fixture which is mounted to the base table in the work area of the vacuum chamber.
2- Initiate stream of electrons on target to set the meters, then re-initiate the beam on a part & weld.
3- Vent the chamber to atmospheric pressure and remove the welded part.
The advantages of this process are numerous. Please refer to our ‘ADVANTAGES‘ web page.
