Methods for producing a cohesive laser bond connection, wherein, in a first method step, a bond element () made from copper is provided, in a second method step, a contact element () made from copper is provided, and, in a third method step, the bond element () and the contact element () are connected to one another in a joined fashion under the action of green laser radiation ().

Method for producing a cohesive laser bond connection and apparatus for forming a laser bond connection

A method for connecting different types of metallic joining partners using a radiation source, the two joining partners, having a different melting temperature, at least indirectly making contact lying against each other in the region of a joining zone, and the radiation source introducing its radiation energy into the one joining partner in a region next to the joining zone. It is provided that, because of the radiation source in the joining zone only the joining partner having a lower melting temperature is melted.
