An apparatus and method for method for joining materials includes a rivet that may extend through a first sheet to be resistance welded to a second sheet. The head of the rivet has a cavity and vents allowing adhesive extruded from a pilot hole to be received in the cavity and vented in a direction parallel to the first sheet. The rivet is deformed to an hourglass shape that fills the pilot hole and displaces the first sheet into the cavity. Rivet dimension allow for holding with a robotic gripper that can be withdrawn before welding. Methods of monitoring joint quality include comparing welding parameter profiles and images of good and discrepant joints.
