Abstract:
1. A device for forming a weld joint at connecting surfaces between two parts, a first part and a second part, consisting of at least partly thermoplastic material, with the two connected parts forming an angle differing from 180°, wherein a heatable element for the vibration or friction welding is provided as an intermediate piece between the connecting surfaces, the heatable element being arranged during heating of the connecting surfaces in an area of the connecting surfaces between the two parts, each of the two parts being arranged on a slide, a first slide and a second slide, a slide drive being provided for each of the slides in order to move the heated connecting surfaces towards each other, wherein an element drive is provided for the heatable element, so that the heatable element as the intermediate piece can be moved or positioned according to the movement or position of the first and second slides, wherein the movement of the heatable element as an intermediate piece is formed from a superposition of the movement of the two parts, each of which is arranged on the first and second slides, and wherein the element drive is derived from the slide drives.
