ABSTRACT:
An automotive frame is assembled by joining fins of extrusions formed of aluminum alloy by resistance spot welding. The fins are formed integrally with each extrusion by extrusion. Alternatively, the extrusions may be joined together through a node part having fins. In this case, the fins of each extrusion are joined by resistance spot welding to the fins of the node part. The node part includes a body formed by extrusion and a side plate penetration-welded to the body by laser welding. The side plate functions as the fins of the node part.
