An analytical model of the laser clad geometry

In this paper an analytical approach to the laser cladding process has been developed and discussed. This approach has taken into account the process speed and feed rate of the powder being supplied for the estimation of clad geometry. The surface tension between the added material and the substrate is used primarily for the calculation of the clad characteristics. The theoretical results are discussed and compared with experimental data. The model is capable of predicting the clad width and depth with reasonable accuracy at low and medium process speeds.
