  • Publication number: 20150000956
    Abstract: An apparatus and method for fastening dissimilar metals like steel and aluminum utilizes a spot welding machine. The metals are stacked with an aluminum body captured between steels. Heat from the welder's electric current softens the lower melting point aluminum allowing an indentation of the steel layer to penetrate the aluminum and weld to an opposing steel layer. The process may be used to join stacks with several layers of different materials and for joining different structural shapes.
