As a flexible and contact-free joining technology, laser beam welding has increasingly gained importance. Processing of alloys with large melting range poses a challenge due to their solidification cracking tendency. Solidification cracks form due to critical stress and strain states of the dendritic microstructure with interdendritic melt. Despite the high industrial relevance, there are only approaches addressing single aspects of the problem, metallurgically or structurally oriented. The research unit "Solidification Cracking during Laser Beam Welding – High Performance Computing for High Performance Processes" aims at developing quantitative process understanding of the mechanisms of solidification cracking and their relation to process parameters.Various experimental data are measured and simulation tools are developed for different scales, which can also be used to generate large amounts of data. Based on this data, the process understanding can be improved. The validation of the models is a central research goal of the research group. Thus, it is important to ensure sustainability of data and software management across sub-projects. Special attention must be paid to the reproducibility and documentation of the data and software, as well as to the interoperability of the programs and data formats.The sub-project "Sustainable data and software management for research software to simulate solidification cracking during laser beam welding" will ensure this for the entire research group. Besides providing the technical infrastructure for storing and sharing data and software, the know-how about continuous benchmarking, performance engineering and data analysis methods is further developed and shared.
