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.
