During deep penetration laser welding a plume of hot metal vapor and particles is ejected by the keyhole. This vapor plume interacts with the incident laser beam by the means of scattering, absorption and phase front deformation. Within this work we present a measurement setup for diagnostics of the interaction characteristics. The setup combines a high-speed video with the measurement of the emitted spectrum of the vapor plume. This allows the location and differentiation between different zones of interaction between the laser beam and the plume. This knowledge will assist in the avoidance of weld defects which are induced by the vapor plume.
