The Fabrication by Projection Welding Techniques of Fine Wire Bridges for Electro-Explosive Devices

Abstract

An improved method for attaching bridgewires to the leads of electro- explosive initiator assemblies was developed. Nickel tabs, to which has been swaged the bridgewire, are projection welded to the contact pins. A discussion of the technique, optimum conditions for welding the nickel tab to several nickel alloys, and an analysis of the weld are presented. Several welded bridgewire assemblies functioned satisfactorily after subjection to standard environmental tests.
