Laser welding with side-gas application and its impact on spatter formation and weld seam shape

Procedia CIRP, 2020
Abstract Spattering is a quality issue within deep penetration laser welding processes resulting in time-consuming and cost-intensive post-processing. In this study, the formation of unconventional weld shapes, e.g. with bulge formation was observed in a lap-joint, while using a side-gas jet to enlargen the capillary opening.
