Laser welding of plastics and metals was normally divided into two types, viz., laser transmission welding (Ref 4,5,6) and laser conduction welding (Ref 7,8,9). The former type is based on the plastic-on-metal lap joint configuration. When the laser passes through the transparent plastics, the laser beam is focused around the interface between plastics and
