摘要：

This paper follows Lemoine's work [1]. It concerns the modelling of cladding with Nd:YAG laser. Now we are interested in cladding with low laser powers (typically P < 800 W). Experimental observations of the evolution of the mass of the clads allows to show two power thresholds. The theoretical study relies on a calculation of fluence provided to the substrate and on a model of heat transfer into the substrate. We suppose that the first threshold is the required power for the melting of the substrate. The second threshold is the power which allows to melt directly the powder during its flight.
