Abstract

Method for producing a component system having a first component with a first component portion and a second component with a second component portion, including the following steps: connecting, in particular welding or soldering, the first component portion, which consists of an aluminum alloy, to the second component portion, which in particular consists of a naturally aged aluminum alloy, a copper alloy or an iron alloy, in particular a steel alloy, so as to form a connection seam; artificially aging the connection seam such that the yield strength of the connection seam is above the yield strength of the first component portion and/or of the second component portion; and deforming, in particular deep-drawing and/or stretch-drawing, the component system.
