Advantages of Electron Beam
The low energy input to the workpiece is possible
because the electron beam process does not depend on the thermal
conductivity of the material as with most conventional welding.
penetrate deeply into the material with a single pass, where
the welding requires several passes to achieve the same weld
depth. Since the heat input is proportional to the fusion
zone(depth x width) the heat input of electron beam welding is
considerably less than tig welding . Electron beam welding keeps
the distortion factor to a minimum.
Benefits from low total
- Minimized deformation and shrinkage of the workpiece.
- Minimized deterioration of the mechanical properties.
These benefits allow for: welding of parts that have been
finished to final dimension, welding in close proximity to
heat-sensitive components, welding of refractory and reactive
materials and welding dissimilar metals not usually joinable by
Freedom from Impurities
The workpiece is not contaminated during the welding process.
This is possible because no mobile foreign atoms are produced
during welding. Electrons do not have chemical or material
properties and the weld chamber is evacuated, which results in
freedom from impurities.
machine adjustments the power, energy, spot size and position of
the beam are under the control of the operator
