Department Laser Technologies
Laser material processing enables the cost-effective manufacture of complex products and realizes innovations in the fields of electromobility and energy generation/storage, lightweight construction and surface functionalization. The Department Laser Technology is responsible for the investigation and further research of a representative range of laser-based joining and separation processes. The theoretical and experimental design of the processes, the integration of system technology as well as the implementation and realization of plant concepts form the center of these investigations. The work is accompanied by numerical simulation of the processes. In addition, modern concepts for process monitoring and data evaluation by means of AI are developed and used to support process optimization.
Head of Department: Fabian Vieltorf
The main research topics
Research Field: Laser manufacturing technology
The laser production technology at iwb deals with basic research on laser material processing and uses modern system technology for process monitoring. With the help of new approaches to data processing, the sensor signals of process monitoring are used to systematically achieve process improvements.
Research Field Leader: Christian Geiger
Research Field: Intelligent Joining System Technology
Intelligent joining system technology represents an interface between the individual research areas in the Laser Technology group. Here, methods for data acquisition and evaluation are adapted and further developed for use in production technology. Modern data processing methods ranging from statistics to machine learning are used to provide practical recommendations for industrial implementation.
