Welding at atmosphere
At present, non vacuum EB welding is mainly used in Germany for welding aluminium, e.g. for cockpit carriers made of aluminium.
The NVEBW method is advantageous for the increased use of high strength fine metal plates in industry. First of all it is possible to achieve high welding speeds, and secondly it allows lightweight designs to be conceived using a combination of various types of materials, e.g. joining aluminium and steel.
As the energy input can be precisely controlled, durable weld-solder joints can be made (in this case the steel stays hard and the aluminium is fused to it).
