Abstract
A method for producing a joining connection between at least two metal sheets or at least two components made of hot-workable sheet metal with a scaling-resistant coating, is provided. The method includes at least one step in which a connection is produced between the at least two metal sheets or sheet-metal components by hot-press soldering, wherein the surface of the metal sheets or components to be connected is pretreated in order to break up the coating.
Claims9
A method for connecting two components made of hot-workable sheet metal, wherein at least one of the components is provided with a scaling-resistant coating on a metal surface, wherein at least one of the components which includes the coating is pretreated in order to form grooves and/or channels in the coating, wherein the grooves and/or channels in the coating extend the entire thickness of the coating down to the metal surface of the component, applying solder to the grooves and/or channels in the coating, and joining the two components with the solder applied to the grooves and/or channels.
