Abstract
An intake device for an internal combustion engine, comprising welded shells joined along a partition line, in which the partition line is provided with a region for producing inclined additional surfaces, which generate a transverse force Q due to their inclination relative to a pressure force D applied for welding the shells. This transverse force Q offsets a transverse force Q which is generated as a result of the inclination of partial regions of the partition line relative to the applied pressure force D. In this way, the transverse forces which arise during production of the intake device may be at least partially offset in the component, so that little or no forces are exerted on the molding tools, and the welding results for the intake pipe may thus be improved.
