Abstract
A welded joint is made between a sheet-steel component and a sheet-aluminum component by way of a lap or web weld. Hat-like clip parts are pushed through openings in the sheet-aluminum component. The clip parts are welded at their bottom to the sheet-steel component and overlap the exposed flat side of the sheet-aluminum component with their flanges, which form the free rims. In order to improve the quality of the weld, an adhesive is introduced into a gap situated between the clip part and the sheet-aluminum component.
