Within the AWT Group, Steigerwald Strahltechnik GmbH is the specialist for chamber machines designed for welding and drilling purposes, as well as for EB generators in high voltage technology (up to 150 kV and over). PTR Präzisionstechnik GmbH is the specialist at producing machines for mass-producing small parts (e.g. cycle type systems) and low voltage EB generators (up to 60/70 kV).
For decades we have been supplying our machines to customers all over the world. We are only too happy to pass on our years of experience and the knowledge we have gained.
The quality demands placed on joining and surface engineering are fulfilled by electron beam (EB) technology to a large extent. The centrepiece of any EB system is the generator, whose basic design is similar to that of a tube in a television set.
The amount of power is determined by the accelerating voltage and beam current. Electromagnetic systems manipulate the electron beam (diverting and focussing).
The power density of the fine working spot is as much as 108 W/cm2. All beam parameters can be infinitely and accurately changed at high speed so that the beam is easily adjusted to the task.
