Method of manufacturing a vehicle body
 A method of manufacturing a portion of a vehicle body, with the portion being at least part of one of a side, an end, a roof, and a floor plate of the body. The method comprises the steps of providing extruded metal plates formed of a light alloy metal with each of the plates having welding edges and integral structural ribs extending parallel to the welding edges on the inner face of the plates, arranging the plates on a jig in position for welding of the welding edges, without an overlap of the welding edges, restraining the plates in a welding position on the jig, and welding the welding edges on the jig by one-sided welding from an inner side of the plates to produce continuous welds. Frame members extending transversely to the structural ribs can be welded on the same side without moving the plate from the jig.
