Correlative high-speed synchrotron X-ray and inline coherent imaging of high-power laser welding

Abstract High-power laser welding is central to electric vehicle (EV) manufacturing, yet keyhole instability and associated defects remain difficult to control due to highly transient process dynamics. Here, we combine inline coherent imaging (ICI) and high-speed synchrotron X-ra...
