Orbitform is offering a forming and fastening process known as hot upset riveting, which is suitable for applications including the assembly of hardening materials such as automotive door strikers.

Hot upset riveting combines electrical current with pressure and time to compress and expand the forming material or rivet to a desired diameter and shape.

Orbitform’s process provides product manufacturers with another quality process for permanent part assembly.

Hot upset riveting complements Orbitform’s orbital forming, spiral forming, roller forming, impact riveting, robotic MIG welding and resistance welding processes and products.

The process begins where its cold riveting counterpart ends.

Although application specific, the hot upset riveting process has proven successful in steel mortise joints with unusual geometry to obtain hole fill in excess of 98 per cent.
