Abstract: This research focuses on laser through transmission welding for thermoplastic materials, experimentation of thermoplastic through transmission laser welding, and a comparison with finite element (FE) modeling of the laser welding process. Thermoplastic through transmission laser welding is increasingly used in industry and manufacturing due to the precise weld location, speed of process, and quality of weld. However, thermoplastic welding parameters are often unknown or thermoplastic welding standards are undeveloped. The comprehensive objective of the experimentation and FE modeling performed in this work is to develop a relationship between melt temperature and laser energy absorption used in thermal welding for PA6 and PA66. Surface exposure experiments are performed on PA6 and PA66 samples to measure thermal profiles. FE simulations are performed to compare thermal profiles and maximum temperatures measured during experimental testing of PA6 and PA66. This work develops a novel experimental testing procedure for studying the thermal properties of PA6 and PA66 thermoplastic materials under a surface exposure loading from laser energy. The thermal behavior of the thermoplastic material showed that the maximum temperature occurs at the beginning of the weld process and is documented in both the experimentation and FE simulations. The findings from this protocol include thermal property behavior and melt temperature points that are measured and compared with literature values. The significant results of this work include experimental development of surface exposure testing for PA6 and PA66 as well as comparison between maximum temperature measurement in experimentation, simulation, and literature values for PA6 and PA66.
