Modern wobble laser welding heads allow a great degree of freedom in the choice of oscillation modes resulting from a superposition of two orthogonal sinusoidal functions. Yet the basic oscillation modes like circular or transversal linear mode are still the most popular in practice. Therefore, unusual oscillation modes with more complex laser spot trajectories were suggested and experimentally achieved. In this way, wavy welds were created into martensitic 22MnB5 steel. The intention was to achieve welds with variable cross-sections, yet with a continuous root. The microstructure and properties of welds were analyzed with emphasis on changes in the heat-affected zone. We aim to provide a deeper understanding of advanced oscillation modes and their impact on the resulting weld quality and mechanical properties.
