Seam in a body outer panel of a vehicle

摘要

Edges of first and second panel plates to be joined together are butted to each other along a seam to be formed under a backing support by a backing member extending along the seam to lie over both of the two panel plates. The backing member being wide enough to extend over both sides of the seam and having a substantially higher rigidity than the panel plates, wherein the butting edges of the two panel plates and the backing member are all welded together along the seam.
