The problem of numerical simulation of temperature field in the process of bimetal melting by the scanning laser for rays focusing in a rectangle and in a circle are considered. The mathematical model of the process is a boundary problem for unsteady three-dimensional nonlinear partial differential equation in the variable domain. Comparison of results of the modeling with different laser beam shape and power distribution is made according to key characteristics
