Contour Laser – Laser-Transmission Welding of Glass Reinforced Nylon 6

Abstract

The effect of contour laser welding parameters (laser speed, laser power, and weld pressure) on T-joint weld strength and meltdown of 30% glass reinforced nylon 6 is presented. For the range of parameters studied, meltdown was a strong function of the energy input, expressed as line energy, and pressure. Maximum weld strength, approximating that of the base material, could be obtained by optimizing the energy input. Weld strength diminished with increasing weld pressure.
