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. In addition, modern concepts for process monitoring and data evaluation by means of AI are developed and used to support process optimization.

Current research covers a broad spectrum of laser-based manufacturing processes. A key technological focus is the application of laser manufacturing technologies to energy storage and energy conversion systems. In several projects at the iwb, laser-based processes are employed along the entire production chain of lithium-ion batteries and solid-state batteries. In addition, the use of laser manufacturing technologies along the hydrogen process chain for electrolyzers and fuel cells is being investigated. The wide range of available sensor systems enables the monitoring of laser manufacturing processes and their continuous improvement.
