Abstract
A method is provided for making a passenger car body structure which has a panel assembly forming at least part of a side, the roof, and end of the floorplate. Each panel has inner and outer spaced metal sheets and a cellular metal core brazed to the sheets and maintaining them spaced apart. To join the panels, a metal connecting member is joined to at least one of the inner and outer sheets and has a projection for use in welding the panel to the neighboring panel. The projection extends in the lateral direction of the panel and is preferably of material thicker than the general sheet thickness of the sheets. A frame member of the body structure may be welded to the panels at the joint.
