Embodiment Construction
[0016] figure 1 A weld material member 14 and a weldable member 18 are shown. Additionally, a projection welding device is indicated generally at 301 . As shown, a plurality of weldable material members 14 are attached to an outer surface 20 of weldable material 18 on which a welded connection will be formed by the welding process, and as shown in FIG. 3, another weldable member 22 may be Positioned in contact with and overlying the welding material member 14 and the weldable material member 18 such that the welding material member 14 can be disposed between the weldable material members 18 and 22 . Then, if Figure 5 As shown, after the welding process, weldable members 18 and 22 are joined by use of welding material 14 at the junction between the two members 18 and 22 .
[0017] Each solder material member 14 is formed of an electrically conductive metallic solder material capable of melting when heated by the application of a sufficiently large electric current. Also, e...

Abstract
A welding material is constructed and arranged to be positioned in electrically conductive relation between exterior surface portions of first and second weldable members at a location where the first and second weldable members are to be joined. The welding material includes at least one welding material member constructed of an electrically conductive metallic welding material capable of melting when heated by application of an electrical current. Each welding material member is mounted on the exterior surface of the first weldable member and then positioned between the exterior surfaces of the first and second weldable members to be electrically conductively disposed therebetween.
