Vacuum metallurgy takes place with melting, shaping, and treating of metals and alloys under reduced pressure that ranges from subatmospheric vacuum pressure to ultra-high vacuum. The process of separating pure metal from mixed metallic particles, alloys, intermetallic and refractory metals by vacuum metallurgy is that the vapor pressures of various metals at the same temperature are different. The metal with high vapor pressure and low boiling point can be separated from the mixed metals through distillation or sublimation. There are three basic reasons for vacuum processing of metals: Elimination of contamination from the processing environment, reducing of the level of impurities in the product, and deposition with a minimum of impurities.

A&J Vacuum Services supplies a full range of vacuum products for the successful application of vacuum metallurgy for clients throughout the world.

Electron Beam Welding (EBW) is a welding process producing a coalescence of metals with heat from a concentrated beam of high velocity electrons. The EBW process is made possible by the use of vacuum pumps fitted for a vacuum chamber which houses the electron beam gun and the metals to be joined. The kinetic energy is transformed into heat on impact on the metal, instantly vaporizing it to a molten stage. Near 25,000 °C heat is generated in the metal as it is bombarded by a stream of high-velocity electrons. This makes it possible to weld much thicker workpieces than is possible with most other welding processes. As the electron beam from the electron gun is tightly focused, the total heat input is much lower than that of any arc welding process. As a result, the effect of welding on the surrounding material is minimal, and the heat-affected zone is small in comparison. The metals most often welded are the super alloys, the refractory metals, the reactive metals, and the stainless steels.

A&J Vacuum Services sells and services a full range of vacuum pumps for electro-beam welding, serving clients around the world for their EBW vacuum needs.
