  • Method for connecting different types of metallic joining partners using a radiation source
    Patent number: 9452490
    Abstract: 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.
