The electron beam technology is used for creating extremely reliable, deep and at the same time narrow and parallel weld seams. Angle distortion, transverse shrinkage and other disturbing influences occurring during welding of delicate component are minimal.
The application spectrum of this method ranges from welding of very fine films to joining of workpieces having a section thickness of more than 100 mm in only one operation. Almost the entire spectrum of metal-based materials and many combinations of such materials can be welded.
There is a great cost savings potential in the design of mechanical components due to alternative component layouts. The high welding speed of the electron beam technology allows for a high productivity in large-series production in electrical and automotive engineering. For the processing of individual components and small series, e.g. for aerospace industry, shipbuilding or rail engineering electron beams have the advantages of being precise and repeatable since they are based on electronic measured and controlled variables as well as on control factors, which offer optimal conditions for automated production processes.
Benefit from our strengths:
Safe welding technology, efficiency, reliability.
Electron beam technology is used in almost all industries and for the solution of both standardized and technically demanding welding tasks.
Automotive industry: large quantities at high efficiency e.g. the complete power train (engine, drive) (figure 1).
Aerospace engineering: challenging special applications, such as helicopter components (figure 2) or satellite tanks.
Power & electrical engineering: large quantities based on materials such as copper and other contact materials e.g. power switching (figure 3).
Rail, ship and medical engineering: safe join connections, e.g. coupler on the ICE train (figure 4) and joining of implants (figure 5).
Mechanical engineering and food industry: small and medium quantities based on a broad range of high-grade steels and the combination of which. Here, components with a weight of up to 50 t can be welded by using the electron beam technology.
Research and Development: Challenging tasks with special materials ranging from tungsten to platinum are implemented in complex designs.
Due to the fact that all important parameters are based on electrical control variables the electron beam is able to measure and to control its processes in a precise manner. Today modern electron beam machines can monitor and control their beam quality themselves.
The accurate positioning of the beam by means of electron optical joint recognition – as the most important link to the component – is performed automatically. Complex secondary processes, such as preheating of the joining area, can be carried out by the beam. Thus, they can be fully integrated into the CNC cycle.
Process control for certain types of defects has already been tested. However, the focus is still on the conventional recording of parameters in the process documentation.
In addition, the electron optics can be used for analyzing the position and the properties of the weld bead.
Today, more and more components are labeled for documentation purposes. This labeling is performed with the same beam that has previously created the weld seam.
