This thesis is directed to laser cladding with powder and a CO2 laser as heat source. The laser beam intensity profile turned out to be an important pa6 Summary rameter in laser cladding. A numerical model was developed that allows the prediction of the surface temperature distribution that is attained with an arbitrarily shaped intensity profile. Input parameters for this model are laser machining parameters and properties of the laser beam, as well as material properties and the absorption of laser energy at the surface. The thermal material properties and the absorptivity were derived from experiments.
