RSR Multi-Material Joining

RSR® is a patented single-step multi-material joining technology that provides manufacturers the ability to join a variety of material combinations, including aluminum castings and ultra-high strength steels.

Resistance Spot Riveting

CenterLine and Howmet Aerospace have partnered to develop the RSR® technology along with the Rivet Delivery System (RDS) to enable multi-material joining with widely used standard spot-welding equipment.

Flexibility Combinations

The RDS equipment has been designed to retrofit onto existing resistance spot welding equipment. This allows for the seamless transition from conventional RSW to joining dissimilar material combinations with RSR all with the same piece of equipment – within the same workpiece even.
