Low Cost Laser System for the Processing of Lightweight Materials

Project Status: finished


The goal of this project is the construction of a low-cost 3D-laser system, which consists of a high-power diode laser and a 6-axial standard industry robot. The adaptation of a temperature dependent laser power control qualifies the system for temperature critical processes such as laser beam hardening. Through the planned integration of an offline programming system TOPLAS 3D, technologically conditioned nonproductive times, for example the expenditure of time for teaching the course of motion, are minimized, which leads to the reduction of production costs. The unit?s potential for laser beam hardening has been proved. Furthermore, the qualification and limits of the unit for the welding of steel DC04 have been investigated thoroughly. The current object of research is the welding of magnesium alloys with the diode laser. In the near future, the usefulness of the diode laser system, as far as the welding of zinc coated sheet metals and the laser beam brazing of lightweight materials is concerned, is going to be investigated.
