Paper Abstract

Modern laser technology is continuously opening up new fields of applications. Driven by the development of increasingly efficient laser sources, the new technology is successfully entering classical applications such as 3D cutting and welding of metals. Especially in light weight applications in the automotive industry laser manufacturing is key. Only by this technology the reduction of welding widths could be realised as well as the efficient machining of aluminium and the abrasion free machining of hardened steel. The paper compares the operation of different laser types in metal machining regarding wavelength, laser power, laser brilliance, process speed and welding depth to give an estimation for best use of single mode or multi mode lasers in this field of application. The experimental results will be presented by samples of applied parts. In addition a correlation between the process and the achieved mechanical properties will be made. For this application JENOPTIK Automatisierungstechnik GmbH is using the BIM beam control system in its machines, which is the first one to realize a fully integrated combination of beam control and robot. The wide performance and wavelength range of the laser radiation which can be transmitted opens up diverse possibilities of application and makes BIM a universal tool.
