Hybrid Laser Welding of Polymers

Most plastic welding systems sold today involve machinery that employs either friction or hot-plate welding technology. These systems involve a contacting operation of an application-specific tool with the workpiece, causing either high mechanical loads on the workpiece or material partially adhering to the tool. If these deficiencies are decisive criteria in the choice of a joining method, a contactless transmission welding technology using infrared radiation promises to be an interesting alternative approach.
