The welding strategy was varied by different geometries of the scan contour, different beam shapes and an adaptive line energy. Different beam shapes were realized using a two-in-one beam delivery fiber. In order to capture the formation of pores, the processing zone was observed by means of X-ray imaging. The formation of spatters was observed using a high-speed camera. With the observation it was possible to separately determine the influence of scan contour and beam shape on the formation of pores and spatters. Finally, these findings were applied to identify beneficial welding strategies to reduce the formation of pores and spatters.
