ABSTRACT:
The present invention provides a process for joining plastics components by a combination of pressing and laser welding, wherein, at the joining points (1) of the components (3, 4), at least a first component (3) has a resilient and/or compressible sealing lip (5), wherein the sealing lip (5) is resiliently deformed by pressing the components (3, 4) together, while the external pressure is maintained, the laser beam is directed onto the joining point (1) and, by purposeful irradiation of the joining point (1), the components (3, 4) are joined together.
