Abstract
A thermodynamic model was developed to describe the quasi-steady
thermal process of a wide thin steel workpiece irradiated by a moving
Gaussian laser beam. In this study, an experiment was done on six steels to
verify this model. The calculated Ac1 and Ac3 depths and temperature cycles
were compared with the measured results. For AISI 4340 steel, correction
coefficients were applied to produce an empirical equation for temperature
cycles above 488.4°C.
