The paper describes the physical aspects of modelling a moving heat source on the outer surface of a steel ring. The work concerns numerical modelling of thermal and structural phenomena in spiral laser heating and cooling in any coolants. The numerical analysis performed in the Abaqus/FEA software was developed to predict the size and quality of the hardened zone. The power distribution and spiral motion of the moving heat source are implemented in an additional DFLUX subroutine (Fortran). The results of the numerical simulation include the temperature field and the predicted zone hardened at different cooling rates. They are the starting point for the analysis and selection of parameters when modelling the hardening process, taking into account phase transformations in the solid state.
