Numerical Simulation of Transmission Laser-Welding Melting Depth on Thermoplastic

Abstract:

The principle of laser welding of combined translucent thermoplastic and absorbance thermoplastics is that laser transmit through translucent material and shoot at laser absorptive material, where the material absorb energy and melt down to complete welding. This paper studied the applicability of basic law of laser transmission welding beam mechanism and light absorption process – Beer-Lamber Law to plastic materials. Numerical simulation model of melting depth was established. Single factor relevance curve and double factor relevance surface were drawn with MATLAB; Impact of laser power, distance between weld zone and lens and scanning speed to melting depth was quantitatively analyzed on melting depth, which provided effective reference for setting parameters in the experiment.
