ABSTRACT:
A pair of metallic components, such as a pair of metallic structural components for a vehicular body and frame assembly, are permanently joined using a magnetic pulse welding process. Initially, a first metallic component is provided having a first aperture that is formed through a first side and a second aperture having a hollow cylindrical flange portion that is formed through a second side. A second metallic component is provided having a surface that extends at an angle relative to the flange portion. The angled surface may be provided in the form of either an enlarged region or a reduced region on the second metallic component. The first and second metallic components are arranged such that the flange portion of the first metallic component overlaps the surface of the second metallic component. A magnetic pulse welding process is performed to cause the flange portion of the first metallic component and the angled surface of the second metallic component to engage one another and become permanently joined.
