Abstract
A girder is described for a vehicle chassis made of at least two sheet metal profiles () composed along their longitudinal edges into a circumferentially enclosed hollow profile (), which hollow profile comprises at least two longitudinal sections () which are both materially joined by way of a joining seam (). In order to provide advantageous constructional conditions it is proposed that one of the two longitudinal sections () consists of an iron material and the other longitudinal section () of the hollow profile () consists of an aluminum material, and that the joining seam () forming a welded/soldered connection between the butt-jointed longitudinal sections () of the hollow profile () comprises an additional material () on the basis of aluminum as solder which is applied into a coating of the iron material in a width (b) corresponding to at least three times the thickness (d) of said iron material
