Multi Beam Technology for Welding Gears/Electron Beam Welded Gears

Electron beam welding of gears and sprockets is one of the pro-beam standard applications. Besides job shop of prototypes or of small and medium series for many renowned automobile manufacturers and their suppliers, pro-beam electron beam machine systems are used for welding daily much more than ten thousand gears worldwide.
In spite of meeting the highest quality requirements the cycle times that can be achieved are above all values achievable by other welding methods.

This is due to the fact that electron beam welding is the only technology allowing for welding at several points simultaneously (multi beam technology). Besides this advantage regarding the cycle time the extremely distortion low electron beam welding method offers the possibility of developing and applying so-called "multi process technologies" by means of the multi beam technology.
In this manner, several production processes can be combined in one process (welding and post weld heating, hardening and tempering etc.). This makes the acquisition of further machine technology unnecessary and time, logistics and of course costs are saved to a considerable extent. For example, it is also possible to combine welding processes with hardening processes.
