A filler-metal weld rod (58) of a filler-metal composition is prepared by providing a mass of metallic powders mixing the metallic powders with a temporary thermoplastic binder to form an injection-moldable mixture (48) and thereafter injection molding the injection-moldable mixture (48) 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 from the injection-molded rod and the injection-molded rod is thereafter sintered to form a filler-metal weld rod (58) with the temporary thermoplastic binder removed in the step of sintering.

Why it's free to use
- Filed July 14, 2005 and granted July 9, 2013. A Canadian patent filed from October 1, 1989 lasts 20 years from filing, so its term ended July 14, 2025.
- Certificates of supplementary protection extend only drug patents, and it isn't classified as one.
- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
