Conclusions 1. A method based on approximation of the real heat source by a combination of Gaussian sources is proposed for calculation of the parameters of the heating of massive bodies by spatially nonmonotonic laser radiation; this makes it possible to represent the desired thermal field as the superposition of known solution. 2. The higher the velocity of the beam right down to disruption of the production parameters of the hardening process, the more vigrously the nonmonotonicity of the spatial distribution of laser radiation in the direction perpendicular to the displacement axis will affect the parameters of the temperature field. This influence diminishes with decreasing displacement rate of the laser beam and with increasing depth of penetration of the isotherm under consideration. 3. Computations of production parameters of the laser hardening of steel 55SM5FA and ShKh15 articles indicated good convergence with experimental data.
