Abstract: Methods of fastening are provided. A method comprises contacting a fastener with a first layer of an assembly at a first location. The assembly comprises the first layer, a third layer, and a second layer positioned intermediate the first layer and the third layer. The first layer, the third layer, and the fastener are electrically conductive. The second layer defines a gap and the first location is in communication with the gap. Electrical communication is formed between the assembly and the fastener. The first layer is fastened to the third layer through the gap in the second layer with the fastener. The fastening comprises resistance welding the fastener to the third layer.

Abstract: A hybrid electrode for resistance spot welding and a method of resistance welding are provided. The hybrid electrode comprises a pin and a collar member. The pin comprises an electrically conductive material and a pin contact surface. The collar member comprises a material that is at least one of less electrically conductive than the electrically conductive material of the pin and less thermally conductive than the electrically conductive material of the pin. The collar member comprises a collar member contact surface, and defines an inner cavity and a longitudinal axis. The pin is at least partially disposed in the inner cavity and the pin contact surface extends away from the collar member and is offset a distance along the longitudinal axis from the collar member contact surface.
