This part is a natural continuation of PART I. In this paper the non-linear analytic - numerically computed methods are presented. For a plate with optional thickness, the radiative heat transfer on both surfaces is taken into account. Temperature dependent materials properties are also considered and this makes these methods competitive with other non-linear ones. Finally, a few analytical examples with use of C-I-N heat source for thermal modelling of laser welding are demonstrated.
