Abstract
A vehicle body assembly is described herein, including a first structural component and a second structural component. The first structural component may be a roof component or a side panel, and include a first part including a first metal and a second part including a second metal different than the first metal. The second part is formed on a peripheral edge portion of the first part and defines a mounting flange for the first structural component. The second part is joined to the first part via an ultrasonic additive manufacturing (UAM) interface. The second structural component is including the second metal and is joined to the second part at the mounting flange via a resistance spot weld (RSW) joint.
