Two metallic members are connected together over a defined area of respective surfaces of the members by providing at least one layer of metal on at least one of the surfaces. The or each layer of metal has at least one elementary component and is of essentially uniform composition over the defined area, and is of essentially uniform thickness over the defined area. The two surfaces are brought into confronting, contacting relationship, and heat is applied to cause the metal of the or each layer to melt, whereby the members are bonded together by an alloy having a melting point in the range from about 500 degrees C to about 900 degrees C.
