Abstract

A method is provided for producing a component connection. The method includes the following steps: provision of a first component consisting of a first material; welding of a ball or a ball-like element, which likewise consists of a first material, to the first metal sheet; provision of a second metal sheet, which consists of a second material that differs from the first; production of a through-hole in the second metal sheet, at least one edge section or the entire peripheral edge of the through-hole being bent over or upwards towards one side of the second metal sheet, thus forming at least one clamping collartype element; assembly of the two components such that the ball or ball-like element projecting from the first metal sheet is introduced sufficiently far into the through-hole from the side of the second metal sheet facing away from the at least one clamping collar-type element that the ball or the ball-like element projects at least partially out of the through-hole on the side of the at least one clamping collar-type element; and welding of the second metal sheet to the ball or the ball-like element and/or to the first metal sheet by the at least partial fusion of the at least one clamping collar-type element, such that fused second material flows into an undercut region between the first metal sheet and the ball or the ball-like element, thus producing an interlocking connection in addition to the bonded connection between the ball or the ball-like element and the second metal sheet and/or the first metal sheet.
