The implementation of load-bearing lightweight structures requires innovative design approaches and advanced manufacturing processes, as for example laser welding, laser-additive manufacturing and laser shock peening. The knowledge about the relationships between process, microstructure and resulting properties enables the specific adjustment of structural properties. Since these relationships are often very complex and laser additive manufactured or laser welded structures generally do not possess homogeneous material properties, highly developed experimental techniques are required, which are supported by suitable assessment concepts and simulations. This makes it possible to develop reliable structures of high durability for industrial maturity in order to minimize human and environmental hazards.
