We present here a study of the scattering phenomena in semi-transparent polymers induced by their compositions in the through-transmission laser welding processes. In a 1st part; an optical model based on Mie theory and Monte Carlo method is used to describe the laser beam behaviour in semi-transparent media. This model permits to estimate the laser power distribution at the interface of the two materials to be welded. A second model based on finite element method allows the temperature field estimation into the both components. The results are validated by infrared thermography in the case of a PMMA and ABS-PC alloy couple.We present here a study of the scattering phenomena in semi-transparent polymers induced by their compositions in the through-transmission laser welding processes.
