What Is Self-Piercing Riveting (SPR) ?

It is a method used to connect sheet materials using rivets, where the rivet is driven into the sheets to clamp them together. Unlike traditional riveting, no pre-drilled holes are required, making it a fast single-step process. Typically, during rivet insertion, the first sheet is pierced, and then as the rivet gets jammed into the second sheet, the second sheet deforms into a button. This process is similar to riveting, but instead of using rivets, the punch deforms the sheets into interlocking buttons.

Through SPR, the sheets are deformed by being held in place by the rivet and form an interlock between them. However, SPR requires access to both sides of the joint. Start by clamping the sheets between a die and an anvil. Then, use a punching tool to drive the rivet through the sheets, piercing the top sheet and causing the bottom sheet to expand into the die. The shape of the die causes the rivet and the bottom sheet to flare outwards, creating a mechanical interlock.

The rivet head can be flush with the top sheet, but the bottom sheet will always protrude to form a button, which usually isn’t pierced. SPR comes in various proprietary processes and often utilizes semi-hollow rivets, though solid rivets are sometimes used as well. Unlike welding, SPR can be used to join dissimilar metals or materials that are not weldable. This has become increasingly important in the automotive industry where combinations of aluminum and steel sheets are used. As a result, SPR is being employed in certain vehicle designs as a replacement for spot welding. SPR is an effective method for joining parts made of aluminum, steel, plastic, or composite materials.

Other advantages include no smoke or sparks, no need for material heating, low noise, and low energy consumption. It is also suitable for pre-coated materials that are not conducive to welding. For example, blind rivets are used in body assembly, where restricted access allows for joint access from only one side. In such cases, the benefits of SPR are null since access from both sides is required to form the rivet upset.
