Abstract

A method produces at least one defined connecting layer between two components, wherein the first component is produced from a first metallic material and the second component is produced from a second metallic material and the first and/or second component has a coating of a third metallic material, the melting temperature of which is lower than the melting temperature of the first and second materials. In this case, the coating of at least one of the components is heated locally to a connecting temperature, which lies above the melting temperature of the third material and lies below the melting temperature of the first material and below the melting temperature of the second material, and is cooled down in order to form a defined connecting layer when the coating solidifies.
