Abstract

The laser cladding process consists in adding a molten blown powder to a partially melted substrate, this in order to change the substrate properties. The aim of this paper is to present different experimental set-up associated with different image processes in order to characterize the powder stream in the laser cladding process. Information such as the particle speed, the powder distribution in function of the nozzle distance are presented. The used algorithms as well as the experimental set-up are presented and detailed.
