Title:
INFRARED LASER WELDING OF PLASTIC PARTS WITH ONE OR MORE OF THE PARTS HAVING A MODIFIED SURFACE PROVIDING INCREASED ABSORBTIVITY TO INFRARED LASER LIGHT
Document Type and Number:
WIPO Patent Application WO/2012/099784
Kind Code:
A3
Abstract:
A method of using TTIr welding to weld together two high transmissivity plastic parts includes providing one or both parts with a modified surface that increases that plastic part's absorbtivity to laser light. The two parts are then laser welded by directing a beam of infrared laser light to the parts which are oriented so that the beam of infrared laser light first passes through one of the parts, impinges the modified surface (or surfaces) at a weld interface where the two plastic parts abut each other to melt the plastic parts at the weld interface, and then passes through the other plastic part.
