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

摘要

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.
