The pro-beam group

The pro-beam company was founded in 1974 as an electron beam subcontractor with two employees and two used machines. Today, after more than 40 years of continuous growth, pro-beam has the status of a medium-sized company and employs nearly 300 people in four locations in Germany and two in other countries. The company operates over 30 electron beam welding machines, five electron beam drilling systems and a number of PACVD (Plasma-Activated Chemical Vapour Deposition) coating systems. The electron beam machines have beam powers in the range of 1 to 45 kW and chamber sizes from 0.05 to 730 m3. The PACVD systems with chamber sizes from 50 litres to 1 m³ work with RF generators (13.56 MHz) in a power range from 1.2 to 5.5 kW. pro-beam processes orders for its customers on up to seven days a week, partly in three-shift operation. This makes pro-beam the largest electron beam subcontractor world-wide and the only company with decades of experience in the potential application fields of welding, drilling and finishing of surfaces by hardening, remelting and alloying as well as deposition welding by means of electron beam technology. Based on its experience from the wide range of contract work in the first 25 years, pro-beam has specified requirements for machine designs the market was not able to supply. In the past ten years, various machine types in electron beam technology have been developed inhouse to production-readiness. pro-beam has beam technology of the highest quality and optimally efficient beam-control technology. Qualitative analyses of weld seams by evaluating various signals can be achieved with standard beam-generating systems.

pro-beam has developed to a supplier of services for complex production requirements with the highest demands on quality. Numerous certificates of quality provide evidence of the appropriate expertise.
