Electron Beam Systems
We have been delivering our machines to customers around the world for several decades. We are happy to pass on these long years of experience and the related know-how to our customers.
PTR STRAHLTECHNIK is the specialist in the GBT-Group for chamber systems for welding and drilling and also for EB generators using high voltage technology (up to 150 kV and more).
The basic principle
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 electron beam
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.
