The production of load-bearing lightweight structures requires innovative design approaches and advanced manufacturing processes such as laser beam welding, laser additive manufacturing, and laser shock peening. A deep understanding of the relationships between process, material properties, and resulting structural behavior enables the targeted adjustment of structural properties. Advanced experimental methods and simulations complement this approach to comprehensively assess the integrity of processed materials and structures. This contributes to the development of reliable lightweight structures with high durability, minimizing stress and hazards for people and the environment.
Our goal is to understand the process-property-structure relationships and optimize the structural integrity of lightweight structures. This is crucial for the development of components and structures produced using technological processes. In addition to laser welding and laser additive manufacturing, we also investigate methods such as laser shock peening and laser heat treatment to improve material properties and residual stress states. We use both experimental methods and simulations in this process.
