  • Welded joint for armored vehicles
    Patent number: 6187451
    Abstract: A welded joint suitable for connecting armor plates in armored vehicles obtained by providing one of the armor plates, or an interconnecting element, with a semi-circular rounded lobe; and welding the lobe to the plate to be joined to form a U-shaped welded region such that the ends thereof are directed to the outside edge of the plate so that a crack formed in the weld will tend to propagate along the weld to the outside of the plate. The joint can be used for lap joints, angled joints, and joints involving multi-layers of plates.
