    摘要: For resistance-welding workpieces of metal, an electrode is pressed against superposed regions of the workpieces and an electric current is supplied to the superposed regions to heat the same due to an electric resistance of the workpieces. The electrode has a body having a tip end for pressed engagement with one of the workpieces, and a matrix of tapered teeth disposed on the tip end of the body except for a center of the tip end. The teeth define recesses therebetween. One of the recesses is positioned at the center of the tip end, and the teeth are progressively higher from an outer circumferential edge of the tip end toward the center thereof.

    摘要: A resistance welding electrode for supplying a current to metal workpieces to weld the workpieces to each other has an electrode matrix of a copper alloy and a plurality of members disposed in the electrode matrix and having portions exposed on a surface of a tip end of the electrode matrix. The members are made of a material having an electric conductivity different from that of the electrode matrix. The exposed portions of the members have a total area which is in the range of 40 to 82% of the entire area of the tip end of the electrode matrix.

    摘要: A die comprises metal-rich sections which form an inner wall and an outer wall of the die, respectively. Gradient sections are disposed adjacent to the metal-rich sections, respectively. Further, a ceramics-rich section is disposed between the gradient sections. A punch comprises an inner ceramics-rich section, a gradient section, and an outer metal-rich section. In the die, the composition ratio of metal gradually decreases from the metal-rich sections to the ceramics-rich section. Similarly, in the punch, the composition ratio of the metal gradually decreases from the metal-rich section to the ceramics-rich section.

    摘要: Disclosed is a molding method for powder particles, which is excellent in molding performance, and which makes it possible to obtain a preliminary molded product excellent in strength by enhancing mutual bonding between particles in the preliminary molded product. A molding apparatus for powder particles includes an outer frame die having a mold space with a lower punch and an upper punch to be slidably fitted thereto. Slight clearances exist between the outer frame die and the lower and upper punches. A mixture is prepared by mixing a powdery raw material with a liquid additive to cause an exothermic reaction therewith.
