Abstract
A capacitive stud welding having an inductive-capacitive welding current supply circuit is provided with a stud and a tunable inductor. The stud is attachable to a workpiece and has an end portion shaped to retain in place on the workpiece at the weld point the flux from the stud to form an optimum weld. The tunable electrical inductor optimizes resonance of the inductive-capacitive welding current supply circuit and the flow of welding current through the stud and workpiece.
