Abstract

We have developed an analytic solution to heat equation in vicinity of steel sample surface, heated by pulsed Gaussian laser beam, taking into account both heat transfer conduction and radiation. Then we performed a new calculation method to build up isothermal generative lines in vicinity of targeted surface. We tried to explain line distortion through comparison with some of our further studies that considered basically conduction phenomenon and that paradoxically performed non-Gaussian temperature experimental profiles.
