Laser beam welding system and process for laser beam welding

摘要

A laser beam welding system has a contact pressure device for fixing components to be welded. The contact pressure device contains a contact pressure element which can be moved from an inoperative position into a contact pressure position. The contact pressure element is constructed to be elastically deformable, and the contact pressure device is designed such that, in the contact pressure position, fixing of the components to be welded takes place by way of a force resulting from deformation of the contact pressure element. In addition, at least one device is provided for increasing the thermal energy absorbed by the components by way of an at least partial absorption of the laser beam.
