Abstract (en)

[origin: WO2019174843A1] The invention relates to a connection arrangement (10, 10B), comprising a first plastic component (20, 20B), a second plastic component (30, 30B), and a closed induction ring (40). The invention further relates to a method for welding a first plastic component (20, 20B) to a second plastic component (30, 30B). The first plastic component (20. 20B) has a first joining region (22) designed as a receptacle, and at one end, the second plastic component (30, 30B) has a second joining region (32) introduced into the first joining region (22). At the joining regions (22, 32), the induction ring (40) is at least partially fused into the two plastic components (20, 20B, 30, 30B) such that at one contact region between a first plastic melt (24) of the first plastic component (20, 20B) and a second plastic melt (34) of the second plastic melt (30, 30B), a material-conclusive connection is generated. In this case, the induction ring (40) is melted into the first plastic component (20, 20B) while forming at least one first undercut (14), and is melted into the second plastic component (30, 30B) while forming at least one second undercut (16) such that between the plastic components (20, 20B, 30, 30B) and the induction ring (40), one each form-fitting connection is created.
