We are your service provider in the following sectors
Electron beam welding
Electron beam hardening
Laser welding
Design meeting the requirements of electron beam welding
Development of electron-beam welding equipment

Electron beam welding totally annuls the classical requirements like:
Same material,
Same material thickness,
Low heat conduction,
Low content of companion elements and
Low carbon content.

The reason for that are the narrow deep seams and the high process speeds. Therefore, this method is not limited to standard materials but may also be successfully applied to special materials, various material combinations, thin-walled and thick-walled structures. Economic solutions are always based on designs meeting the requirements of electron beam technology since the technological advantages of electron beam engineering, weld joint testing and savings in the processing operations are combined.
The clever and extremely cost-saving component design simply uses the specific features inherent to electron beam welding:

Narrow weld seams due to energy input = 1% in comparison with TIG or MAG seams - resulting in minimum shrinkage and minimum distortion
Narrow heat-affected zone - permits relief of welding stresses through equalisation with the elasticity of basic material

Our core competence is laser welding of provided parts. With the laser, very slim welds with a large depth-to-width ratio can be achieved.

Due to the high processing speed, the thermal load is low and the distortion is minimal. Contactless welding makes it possible to process complicated seam geometries and hard-to-reach areas within the workpiece. As a rule, the welding joint is fused from proprietary material.

If required, an additional material can be added via a wire feeder. With the laser, a wide range of materials can be welded without oxide (steel, stainless steel, cast iron, aluminum, cast aluminum, titanium, Hastelloy, Inconel,...)
