Abstract
A method of interconnecting a first element 1 and a second element 4 by means of laser welding, the first element 1 consisting at least partly of glass or ceramics and the second element 4 consisting at least partly of metal, the bond between both elements being formed by the glass or ceramic part of the first element 1 and the metal part of the second element 4, characterized in that a metal auxiliary element 3 is bonded to the glass or ceramic part of the first element 1 by means of a solid-state bond 2, after which, substantially without heating, the metal part of the second element 4 is welded to the metal auxiliary element 3 by means of a laser beam 5.
