The work describes the physical aspects of modeling the heat source movement around the perimeter and its proposed distributions. This study concerns numerical modelling of thermal phenomena in spiral laser heating of shaft made steel. Numerical 3D analysis is developed for the prediction of heat affected zone in Abaqus/FEA software. Power distribution of spirally moving double heat source is implemented into additional DFLUX subroutine, written in Fortran programming language. The model of heat source motion takes into account the size of heat affected zone. Results of numerical analysis include temperature field, predicted heat affected zone and cooling rates. These results are a start point for the analysis of thermomechanical phenomena with the consideration of phase transformations in solid state.
