<p>A girder is described for a vehicle chassis made of at least two sheet metal profiles ( 4, 5 ) composed along their longitudinal edges into a circumferentially enclosed hollow profile ( 1 ), which hollow profile comprises at least two longitudinal sections ( 2, 3 ) which are both materially joined by way of a joining seam ( 10 ). In order to provide advantageous constructional conditions it is proposed that one of the two longitudinal sections ( 2, 3 ) consists of an iron material and the other longitudinal section ( 2 ) of the hollow profile ( 1 ) consists of an aluminum material, and that the joining seam ( 10 ) forming a welded/soldered connection between the butt-jointed longitudinal sections ( 2, 3 ) of the hollow profile ( 1 ) comprises an additional material ( 12 ) 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</p> |
