ABSTRACT:
Panel assembly for automobiles such as a door panel assembly, a bonnet lid and a trunk lid has an outer and inner panels which are welded together along the peripheral portions. The inner panel is formed at the periphery thereof with one or more projections so that thermally insulative spaces are formed between the panels. The periphery of the outer panel is folded over the periphery of the inner panel so that the edge of the outer panel is laid on the projections and welded thereto at the projections. Due to the existence of the spaces, it is possible to eliminate any thermal deformation of the outer panel caused by the welding heat.
