GAP BRIDGING IN LASER TRANSMISSION WELDING OF PA6

摘要

Gaps in weld seams are an obstacle for applying the contour welding strategy in laser transmission welding of polymers. This paper examines the effect of laser (power) and material (carbon black level) and geometric (gap thickness) parameters on the shear strength of PA6 lap welds. Assemblies were made using a continuous wave diode laser in a contour welding mode.
