Abstract

The features of thermal processes in steels during laser heating without surface melting have been considered. A formula has been proposed for determining the temperature along the depth of a metal in the case of heating by a surface heat source with constant intensity. Expressions have been given for threshold values of laser radiation power density: the minimum, at which stationary temperature on the metal surface reaches the hardening temperature, and the maximum, at which the surface temperature in the center of the beam reaches the melting point of the metal. It is shown that for engineering applications, the change in thermal conductivity coefficient with temperature can be neglected and taken as constant.
