Abstract
The invention relates to a method for laser welding at least two components made of plastic, particularly a pipe and a carrier plate, wherein the first component at least in certain regions has a relatively high permeability for the laser beam used during laser welding. The second component at least in certain regions has a relatively low permeability for the laser beam used during laser welding. A compact design of the components can be achieved if the laser beam reaches the respective weld location by means of refraction and/or reflection during laser welding.

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.
A method for laser welding two components constructed of plastic, comprising:
- providing two components having an absorbing effect for a laser beam used during laser welding, and
- 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.

- 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 laser beam is irradiated parallel to a gap extension direction running generally transverse to the gap width into the gap, and
- wherein the gap width is selected from one of:
- i. approximately equal to a diameter of the laser beam, and
- ii. maximally up to about 10-times bigger than the diameter of the laser beam.
