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.

Welded joint between a sheet-steel component and a light sheet metal component, and a welding method

A joint between a sheet-steel component and a sheet-aluminum component is welded by a lap or web weld with the aid of an additional part connected to the sheet-aluminum component at the rim and welded to the sheet-steel component. To make the welding of covering panels manufactured from aluminum to frame parts manufactured from steel sheet simpler and cheaper in production, the additional part is manufactured exclusively from an iron material and lock-seamed to the rim of the sheet-aluminum component.
