BONDING TUNGSTEN WITH A FUGITIVE ALLOY BINDER

摘要

A method of forming a tungsten-to-tungsten joint which comprises depositing on at least one of the faying surfaces a thin film, foil or coating of an alloy consisting essentially of, in weight percent, 55-75 percent nickel, balance iron, pressing the faying surfaces together, heating the joint area to just above the melting point of the alloy in an inert atmosphere to produce a joint which has a remelt temperature approximating the melting point of the tungsten-base metal.
