Electron beam welding (EBW) is a fusion welding process in which a beam of high-velocity electrons is applied to the materials being joined. The work-pieces melt as the kinetic energy of the electrons is transformed into heat upon impact. Raising electrons to a high energy by accelerating them to roughly 30 to 70 percent of the speed of light provides the energy to heat the weld. The beam penetrates deeply, making it possible to weld much thicker workpieces than is possible with other welding processes.
The electron beam is always generated in a high vacuum. Also the welding is
most often done in vacuum to prevent dispersion of the electron beam. The high
vacuum enables welding of higly reactive materials, like titanium or
zirconium.
With high enough energy in the beam, welds up to 10 cm deep in stainless steel,
or 30 cm in aluminium can be made, at width to depth ratio up to 30 : 1.
