The invention steel, tie tyanyum such as a refractory material or of aluminum, magnesium-steel, the pulse current active method for friction stir welding tulyong tungsten carbide sintered body is used to the friction stir welding tool of different materials in a spark plasma sintering apparatus, such as titanium relates to a method of manufacturing using, a tungsten carbide powder (WC) powder and the step of filling in the mold with a graphite material, and the mounting step of mounting a tungsten carbide powder filling the mold in the chamber of a spark plasma sintering apparatus, the interior of the chamber and the forming step and the evacuation step of evacuating, while temperature rise in accordance with the temperature rising pattern is set, while maintaining a constant pressure in the tungsten carbide powder in the mold for molding to reach the final target temperature, maintaining the pressing pressure in a subsequent molding step and it includes a cooling step for cooling the interior of the chamber. According to the method this friction stir joining tulyong manufacture of tungsten carbide sintered body, as by using a pulse current active method to the discharge plasma sintering machine is suitable for friction stir tool for bonding the tungsten carbide relative density can be more than 99.5% of high density when manufacturing and short in a single step particles at the time growth is hardly homogeneous tissue, high toughness, high wear resistance, and while having a high strength can be produced a homogeneous sintered body with no difference in internal / external properties, by being manufactured with only tungsten carbide alone material excluding the sintered jojae such as cobalt down to the advantage of simplicity, and cost of the manufacturing process, grade water provides a stronger high toughness, high wear resistance and high strength compared with sintered bodies added with sintering jojaein cobalt.
