Abstract
This paper presents a three-dimensional (3-D) transient thermal model of spot Laser Transmission Welding (LTW) solved with the finite element method (FEM). Unreinforced nylon 6 temperature-dependant properties were employed for a lap joint geometry. The heating and cooling stages in a spot laser welding process were addressed. The spot weld dimensions obtained from the model were compared with the experimental weld dimension data, and were in good agreement. It is shown that the thermal model is capable of accurately predicting the temperature distribution.
