Abstract
A first metal member is contacted with a second metal member. A metal fastener is provided including a core and a cladding disposed upon the core. The fastener is driven through the first member and into the second member, inducing friction between the fastener, the first member and the second member for at least locally melting portions of the cladding, the first member and the second member to form a flowable material that solidifies and metallurgically bonds the fastener to the first member and the second member for attaching the members together.
