Abstract
A weld joint between two structural elements out of different metallic carrier materials is described, in which at least approximately unmixed weld-joint-interface between the two elements made in such a manner, that on the one side of the interface only metal out of the one carrier material and on the other side only metal of the other carrier material is present. For example, the weld-joint-interface is made by an electron-beam welding. The surface of the weld joint can be enamelled and the welding of the two elements can be performed by a normal melt-welding method, in which welding material out of the metal of the respective carrier materials is laid on.
