Optimizing automated joining with self-pierce riveting
Modern vehicle manufacturing faces increasing challenges: lightweight construction, mixed-material designs, and the demand for high-strength, reliable joints. Traditional methods like spot welding often fall short - especially with aluminum and advanced steels. That’s where self-pierce riveting with Henrob comes in. Our technology combines Henrob rivet setters with precision-engineered rivets to deliver clean, strong, and repeatable joints - without pre-drilling, heat, or fumes. Whether joining aluminum to steel, composites to metals, or similar materials, Henrob ensures structural integrity and process efficiency.
Finding the right rivet for a demanding application isn’t easy. That’s why we design and manufacture our rivets in-house, offering tailored solutions backed by joint development, testing, and global support. With Atlas Copco, you get more than a joining system - you get a partner in performance.
The main steps in the self-pierce riveting process
Self-pierce riveting (SPR) is a dual-sided method of joining two or more pieces of material using a rivet without the need for a pre-drilled hole or a thermal process. The basic self-pierce riveting process involves driving a semi or fully tubular rivet through the material layers to be joined, into a die which causes the tail of the rivet to flare out into the bottom material and form a mechanically-interlocking joint.
