Other fields of applications for Titanium materials are, for example, medical implants for which pure titanium is preferred over its alloys. The pins of the implant, shown in Figure 9, need to be welded into the base plate. The electron beam hits the pins from the flat back of the plate. Electron Beam Welding (EBW) is a fusion welding in which coalescence is produced by heating the workpiece due to impingement of the concentrated electron beam of high kinetic energy on the workpiece.
As the electron beam impinges the workpiece, kinetic energy of the electron beams converts into thermal energy resulting in melting and even evaporation of the work material. Electron beam (EB) welding is a fusion welding process whereby electrons are generated by an electron gun and accelerated to high speeds using electrical fields. This high speed stream of electrons is tightly focused using magnetic fields and applied to the materials to be joined.
The beam of electrons creates kinetic heat as it impacts with the workpieces, causing them to melt and bond together. Electron-beam welding (EBW) is a fusion welding process in which a beam of high-velocity electrons is applied to two materials to be joined.
The workpieces melt and flow together as the kinetic energy of the electrons is transformed into heat upon impact.
EBW is often performed under vacuum conditions to prevent dissipation of the electron beam.

At that time electron beam welding was thought of in the same terms as arc or gas welding, namely as a process using a suitable source of heat, which had the particular advantage that gas sensitive metals were protected from reaction with the atmosphere.
The breakthrough in industrial electron beam welding came in with the requirement to butt weld together 5 mm thick plates of Zircaloy. Electron Beam Welding Process is a fusion welding process in which a high-velocity electron beam is used to join two metals together. The high-velocity electron beam when strikes the weld area of two metal pieces and very intense heat is generated which melts the metal and they fuse together to form a strong weld.
The whole process is carried out in a vacuum chamber to prevent it from. temperature ﬁeld of a large complicated Al alloy structure during electron beam welding (EBW), aiming to control the ﬁnal distortion of the welded structure. The actual workpiece is about 1m in length, with over 8m aggregate weld length. Because a much ﬁner mesh was required to describe the electron beam heat source, computational work would be substan- tially increased due to the three Cited by: Electron beam welding is a fusion joining process performed in a high-vacuum environment.
An electron gun produces a finely focused beam of electrons that converts energy to heat upon contact with the target metal. This results in minimal distortion, no oxides and incomparable weld strength. The fusion of the base metals reduces the need for filler metals. The beam of electrons is maneuvered.
