Uam resistance spot weld joint transition for multimaterial automotive structures

A method for manufacturing a multi-material component, comprising:

• providing a first component comprising a first material;
• providing an insert comprising a second material that is different than the first material;
• joining the insert to the first component via an ultrasonic additive manufacturing (UAM) interface;
• providing a second component comprising the second material;
• and
• joining the second component to the insert.

A vehicle body assembly, comprising:

• a first structural component including:
• a first part comprising a first material;
• and
• a second part comprising a second material different than the first material,
• wherein the second part is formed on a peripheral edge portion of the first part and defines a mounting flange for the first structural component,
• wherein the second part is joined to the first part via an ultrasonic additive manufacturing (UAM) interface;
• and
• a second structural component comprising the second material, wherein the second structural component is joined to the second part at the mounting flange via a resistance spot weld (RSW) joint.
