Patent ID: 8366860

Claim:
A method for laser welding at least two components constructed of plastic, comprising: providing a first component which at least in certain regions, has a relatively high permeability for a laser beam used during laser welding such that the first component is generally permeable for the laser beam, providing a second component which at least in certain regions, has a relatively low permeability for the laser beam used during laser welding such that the second component is generally absorbable of the laser beam, positioning the two components relative to each other in such that between the two components, a gap with a predetermined gap width is present, wherein the gap is covered by a selected one of the two components and that the laser beam penetrates through the selected one of the two components into the gap, wherein the laser beam is irradiated parallel to a gap extension direction running generally transverse to the gap width into the gap, and wherein the laser beam reaches a respective weld location by means of at least one of refraction and reflection during laser welding.
