Abstract

Method and apparatus are disclosed for welding electrical contacts onto springs. A billet of contact material is first welded to two contact springs and, after welding, is cut in two parts leaving one contact on each spring. The method provides rapid and precise means for attaching precious metal contacts to spring material.
