Compared to conventional welding processes, electron beam welding (EB welding) offers completely new perspectives in terms of material pairings, workpiece geometries, welding depths, temperature impairment and manufacturing costs.
EB welding is a joining process that we offer in addition to brazing. This allows us to cover a very wide range of design options for existing and new constructions. As a result, there are hardly any limits to design and creativity. Be it a simple stress-relieving annealing or the setting of specific properties – with the possibility of carrying out the heat treatment of welded components in our own company, we round off our all-inclusive offer.
In electron beam welding, both joining partners are melted and combined after solidification. So no additional material is required.
Thanks to the so-called deep welding effect, we can join steel components up to a welding depth of 50 mm. The weld seam width remains less than 2 mm. This results in high-strength joints coupled with very low distortion due to the moderate heat input.
EB welding takes place in a vacuum chamber that largely prevents oxidation of the weld seam. This means that we are also able to weld more sensitive materials, such as titanium and its alloys.
EB welding creates a very high energy density on the surface of the components, which means that refractory materials, such as molybdenum or tantalum, can be welded without any problems.
EB welding can be used to join not only individual materials, but also a large number of combinations of different materials or material families. For example, copper, nickel, cobalt and various steel alloys, sometimes also with cast alloys, can be joined together, while foreign connections are rather difficult with titanium and aluminum alloys.
Another advantage of EB welding is certainly the possibility of welding complex welding geometries, difficult contours and different wall thicknesses, etc. Furthermore, it is not necessary to weld “into the gap”, but the construction can also overlap.
Involve us as early as possible in your decision-making process and we will show you ways in which you can use the joining technology of EB welding profitably. Their designs can be made simpler and often lighter, which in turn has a positive effect on the profitability of an assembly.
Electron beam welding is a mechanical process that ensures excellent reproducibility. Parameter determination can be a time-consuming affair due to the many factors influencing the welding process. However, once this has been done, the high quality of each individual component is ensured.
EB welding often requires post-processing, such as turning off a bath support or various tests (X-ray, ultrasound, crack tests). We are happy to do this for you directly at our location, as we can cover these services through partners in our immediate vicinity.
