Abstract
En 中文
• Dynamic melt pool surface topography evolution observable with multi-detector Electron Optical operando imaging. • Detector bias voltages suppress thermionic contribution to detector signal during melting. • Backscattered electron dominated detector data usable for surface gradient computation. • Modelling confirms melt pool dynamics remain unchanged by observation.
