METHOD FOR PRODUCING A COMPOSITE PART BY TRANSMISSION LASER WELDING

摘要

The present invention relates to a method for producing a composite part by transmission laser welding, comprising the steps: a) flat arrangement of a multilayer film (2) comprising a joining layer on a hard plastic part (1) such that the joining layer abuts the hard plastic part (1), wherein the joining layer comprises an absorber for laser light, b) pressing the multilayer film (2) onto the hard plastic part (1) using a pressing tool (4) pervious to laser light, and c) irradiating the arrangement obtained in step b) with laser light from the side of the multilayer film (2). The invention further relates to a composite part that can be obtained by said method and to a composite part welding arrangement used in said method.
