Abstract
A method is provided for the projection electric resistance welding of a component to a laminated metal member. The laminated metal member is comprised of top and bottom metal sheets adhered together by a polymer layer provided between the top and bottom metal sheets. A plurality of projections is provided on the component and the projections extend toward the top metal sheet of the laminated metal. Force is applied to the component and the projections have a pointed shape so that the projections pierce through the top metal sheet and contact the bottom metal sheet. Weld current is then applied to flow through the projections so that the projections are electric resistance welded to both the top and bottom metal sheets.
