Title:
THERMAL ASSISTED SELF-PIERCING RIVETING FOR HIGH STRENGTH 7XXX ALUMINUM
Document Type and Number:
WIPO Patent Application WO/2023/066138
Kind Code:
A1
Abstract:
A self-piercing riveting system includes a localized melting system that locally melts a target location on a metal substrate and a driver that drives a rivet into to the metal substrate after the target location is locally melted. A method of forming a joint with a self-piercing riveting system includes locally melting a target location on the at least two metal substrates. The method also includes driving a rivet into the target location, optionally with a driver, after locally melting the target location such that the rivet pierces the at least two metal substrates at the target location.
