ABSTRACT:
This application relates to a method and apparatus for welding together small oxide coated components by driving a sharp edge or point of one part into a face of another part and then discharging electrical energy, for example, a capacitively stored electrical current through the joint. Precision micrometer control of the distance one part accelerates toward the other along with continuously adjustable spring tension are used to program the inelastic collision of the two parts. The electrical discharge circuit is controlled to provide a controlled arc after collision.
