Paper Abstract

We present in this work the parameters study in case of laser cladding (stellite 6 onto stainless steel) with a pulsed Nd:YAG laser and sprayed powder. We characterize the clads by geometrical consideration (cross-section) that allows us to obtain different results concerning laser parameters: particularly the pulse energy (fluence) and the pulse duration. The clad starts up above a fluence threshold and the quantity of melted powder reaches a constant value above a pulse duration. This pulse duration value depends directly on the frequency and powder thermal properties. From those results and a study of laser/powder interaction, we develop an analytical model. This model evaluates, from the cross-section, the melted powder quantity.
