Abstract :
In the laser cladding processes a powder is placed on the surface of the workpiece and heated beyond the melting point by the beam. The laser produces the fusion of the base material and the powder particles producing, during the cooling process, a layer with a chemical composition close to the fed material. This work wants to compute these effects which are basically the heating of the fed material when flying under the laser beam and the decreasing of the beam power due to such heating
