GRAZ, Austria—Engineers at the Graz University of Technology recently developed a new process that enables adhesive-free joining of metal and wood components.

Researchers have developed a way to join steel and aluminum sheets using cold-extruded pin structures.

RICHLAND, WA—Engineers at the Pacific Northwest National Laboratory here have developed a new process for joining aluminum and steel. Friction stir dovetailing was inspired by assembly techniques used in woodworking.

Lightweighting is the No. 1 challenge facing automotive engineers today. Manufacturers are scrambling to build vehicles that contain a variety of weight-saving materials, such as aluminum, carbon-fiber composites, high-strength steel, magnesium and plastic.

The need to reduce vehicle weight has spawned myriad new technologies for assembling aluminum, high-strength steel and other materials. These new technologies include self-piercing rivets, flow-drilling screws and friction-stir spot welding.

WARREN, MI—General Motors engineers have developed a technique to join steel to aluminum with resistance spot welding.

Greater use of aluminum and other lightweight materials is increasing demand for structural blind rivets.
