<p>A filler-metal weld rod of a filler-metal composition is prepared by providing (20) a mass of metallic powders, mixing (22) the metallic powders with a temporary thermoplastic binder to form an injection-moldable mixture, and thereafter injection molding (24) the injection-moldable mixture at an injection-molding temperature above the thermoplastic temperature of the thermoplastic binder to form an injection-molded rod. Any excess thermoplastic binder is removed (26) from the injection-molded rod, and the injection-molded rod is thereafter sintered (28) to form a filler-metal weld rod, with the temporary thermoplastic binder removed in the step of sintering.</p> |
