Abstract

This study developed a thermodynamic model to investigate the quasi-steady thermal process of a wide thin steel workpiece irradiated with a moving Gaussian laser beam. Equations were established for the temperature distribution and the Ac1 and Ac3 boundaries. The temperature distributions for diverse thicknesses were compared with that for infinite thickness at different laser traverse speed. The lag of the peak temperature relative to the center of laser beam is found to be limited.
