Abstract: An improved apparatus and method of joining two metallic components prior to making a full seam weld is disclosed. A first inner structural metallic component has at least one neutral zone, an inner surface, an outer surface and an aperture located in the neutral zone. A second outer structural metallic component has at least one neutral zone, an inner surface, an outer surface and a dimple with a raised portion on the inner surface and a recessed portion on the outer surface. The method uses the steps of joining the first and second metallic components so that the first component outer surface and the second component inner surface are directly adjacent each other, and joining the two structural metallic components by forming a full seam weld between the two components.
