Abstract
A method is proposed for welding a first component part to a second component part, the energy to melt melting regions being supplied by a laser beam. In this context, the laser beam is directed through the first component part, which is made of a nonabsorbing material, to the second component part. The second component part is made of a material which strongly absorbs laser beam. At least one stop is provided outside melting regions.

A method for welding a first component part to a second component part, comprising:
- causing a laser beam to supply an energy to melt melting regions of the first component part and the second component part, the first component part being made of a material that only weakly absorbs the energy of the laser beam, and the second component part being made of a material that strongly absorbs the energy of the laser beam;
- directing the laser beam all the way through the first component part to the second component part;
- pressing the first component part and the second component part against each other from a point of welding taking place;
- and
- providing outside the melting regions at least one stop by which a movement of the first component part and the second component part toward each other is limited.

- pressing the first component part and the second component part against each other from a point of welding taking place;
- and
- angling the first component part and the second the component part to each other in the melting regions before welding, so that, during welding, a preferred exit of molten material on one side of the melting regions is effected.
