Abstract

In this article the quality control of laser marking/engraving of clay tiles using a high power diode laser (HPDL) has been investigated. A one-dimensional analytical model with quasi-stationary situations in an isotropic and inhomogeneous workpiece with a parabolic melt pool geometry being assumed, was successfully developed. The theoretical results were compared with the experimental data. The predicted melt pool depth and the experimental values were in relatively good correspondence for values of the incident laser energy density (>15Wmm-1s-1/2), in spite of simplifications introduced during modeling. At the relatively large values of laser energy density, the assumption of parabolic melt pool shape and one-dimensional heat transfer no longer holds true.
