Lasers are being widely used in the material processing industry lately. In this work, study is performed on the resluting temperature and stress distribution, the width and depth of the melt pool in the heat-affected zone during material processing with a high energy Gussian laser beam. A three-dimensional enthalphy-based mathematical model is developed to study the effect of high energy laser beam on the formation of molten pool. The mathematical model is based on a three-dimensional transient heat equation taking into consideration the power intensity of the Gussian laser beam and phase diagram of the material. A computational algorithm is implemented to evaluate the temperature distributions as well as shape and size of molten pool. The numerical solution with the applied heat flux and convective boundary conditions is obtained usign a 3-D finite element code.
