| Abstract: |
The electron beam is a tool with high energy conversion efficiency which is by and large independent of the type of metal. Its high power density qualifies the non-vacuum electron beam as an outstanding energy source for the well-known NVEB welding as well as for high speed cutting and heat-treatment. After material processing, parts can also labelled with individual markings or company logos by electron beam for means of quality assurance, easier identification or decorative purposes. Welding is possible with or without filler wire or shielding gas, depending on the application. The NVEB-cutting process employs a co-moving cutting head with a sliding seal for extremely high cutting speeds such as 17 m/min for 2.5 mm thick stainless steel producing high quality edges. Due to direct removal of fumes and dust, NVEBC with local suction is an exceptionally clean and fast process. Welding is possible directly after cutting, without further edge preparation. Moreover, material can be permanently marked using the electron beam to assure secure identification of individual parts for reasons of quality control or protection against counterfeit parts. The potential directions of development of non-vacuum electron beam technologies are discussed.
