	Capacitor discharge fasteners have a small pip under the weld end which melts during the arc and welds at the end of the fastener to the material; this is assisted by spring pressure from the welding gun. The process is completed from one side only and leaves a smooth and usually unmarked reverse side due to the extremely low weld penetration depth.
