Abstract

An apparatus for joining, in particular laser welding, two components, in particular plastics components, comprises—two workpiece receptacles (1, 3) for respectively holding the two components (2, 4) to be connected, —in each case one bearing element, preferably a bearing plate (7), for each of the workpiece receptacles (1, 3), —a clamping drive (SA) for at least one bearing element for feeding and bracing of the two components (2, 4) held in the workpiece receptacles (1, 3) during the joining process, —a controller (9) for the clamping drive (SA) and in particular a laser welding device (LS), and—a mechanically loose coupling between the clamping drive (SA) and bearing element (7) such that the two workpiece receptacles (1, 3) are tiltable towards one another during feeding and bracing. Also disclosed is a method for operating such a joining apparatus during a joining process of two components (2, 4) held in the workpiece receptacles (1, 3), in particular during a laser welding process.
