ABSTRACT:
Disclosed is a novel electric joining method and apparatus that can overcome the defects associated with the prior art while taking advantage of the technology for the pulse excited sintering process such as spark plasma sintering process or the hot-press joining process. According to the present invention, an electric joining apparatus for joining a plurality of members to be joined at the joining surfaces thereof, comprises: a pair of current-currying electrodes13, 16capable of contacting with the members so as to apply electricity to the members; a power supply17connected to the pair of energizing electrodes for supplying the energizing electrodes with at least either one of a DC current or a pulsated current; and a pressurizing unit14for compressing each of the pair of electrodes against the joining surfaces, wherein the pair of members are sandwiched between the energizing electrodes and applied with at least either one of the DC current or the pulsated current from the power supply under a desired pressure, thus to be joined, without using a die made of graphite.
