method of producing same. Representative claims 1 and 7 read
as follows:
1. A welded joint between a sheet-steel component and a
light sheet metal component, the two components being welded
together with at least one steel clip part having a hat-like
shape defined by a central portion having a bottom region
which projects to the sheet-steel component through an opening
arranged in the light sheet metal component, a flange
configured with a free rim resting on a free flat side of the
light sheet metal component and portions between the central
portion and the flange raised relative to the central portion
and the free rim such that opposite sides of the light sheet
metal component directly contact the free rim and the sheet-
steel component and a gap is defined directly underneath an
area of the raised portions which face the light sheet metal
component such that an outer edge of the free rim is
prestressed directly against the light sheet metal component
in a state when the bottom region has been joined to the sheet
steel component with the gap remaining, and an adhesive
arranged in the gap to adhesively bond the sheet steel
component and the light sheet metal component together.
7. A method for welding a sheet-steel component to a
light sheet metal component by a weld produced by electric
resistance welding, comprising the steps of providing the
light sheet metal component with an opening in a region of the
overlap with the sheet-steel component, inserting into the
opening a hat-shaped clip part having a central portion with a
bottom portion configured toward the sheet-steel component
through the opening arranged in the light sheet metal
component, a flange forming a free rim portion facing the
light sheet metal part and offset portions between the free
rim and the central portion to define a gap between the offset
portions and the light sheet metal part such that the clip
part overlaps an exposed flat side of the light sheet metal
component, welding the bottom portion of the clip part to the
sheet-steel component by electric resistance welding, thereby
prestressing an outer edge of the free rim portion directly
against the light sheet metal part and compensating play due
to the offset portions which define the gap between the clip
