Abstract
A method for joining individual pieces of material together includes the steps of heating the pieces to be welded together, at least one of which consists of a metal matrix with a relatively low melting point and a reinforcement material distributed therein, the reinforcement having a relatively high melting point. The other piece may be a similar metal matrix composite, or may be a metal or alloy which is to be joined to the first piece. The pieces are heated to a temperature which is above the melting points of the metals and below the melting point of the reinforcement. The pieces so heated are brought into contact with one another and then cooled to a temperature below the melting points of the metals. One technique for practicing the method of the invention is that of capacitor discharge welding.
