Research profile

The LMP+ working group aims to characterize, understand and further develop the processes of laser material processing. We want to create new knowledge and thus identify new approaches. We are pursuing sustainability and resource conservation from several angles:

• Increasing efficiency and minimizing the resources required for the laser beam processes themselves
• Saving resources by optimizing components in terms of shape, material mix and functional integration
• Reduced resource consumption during use through reduced weight, improved functionality and increased service life

In addition to research and development in the area of individual processes, process chains are increasingly being considered in terms of dependencies, interactions and synergies. Laser material processing includes joining, additive, subtractive and surface engineering processes and process steps as well as special processes such as laser beam bending or combined approaches.

The research and development work concerns the analysis of process behaviour, process and parameter development, process monitoring and control, quality assurance and system technology as well as the characterization, analysis and testing of samples and components. Experimental investigations are combined with calculations and simulations using analytical and numerical models. Extensive in-process and post-process data means that data preparation, analysis and visualization are further areas of responsibility. Based on an in-depth understanding of the established or known process concepts as well as the fundamental processes and interrelationships, the focus is often on the further and new development of processes and procedures.

Current cross-process topics include

• Highly dynamic, fast, safe laser beam machining processes with functional energy distribution from the micro to the macro range
• Process-functional interfaces with the distinction between process-influencing ("acting") and information-providing ("reporting") functions of interfaces and surfaces in or during laser material processing processes
• Laser beam-based production technology for a multi-material design of structures and for graded material compositions
• Laser beam-based production technology for hydrogen technologies for applications in the fields of hydrogen production (electrolyzer), utilization (fuel cell) and transport (tank)
• Machining-oriented laser material processing (see LMP+ @ ISF).
