  • Brazing wire, forming method of brazing wire and forming mold of brazing wire
    Patent number: 11845146
    Abstract: A brazing wire includes a brazing tube having an inner cavity and a flux filled in the inner cavity. A trench is provided on an outer peripheral surface of the brazing tube, and the trench extends along an axis of the brazing tube or spirally extends around the axis. A forming mold of the brazing wire includes a mold body having a molding cavity therein. An inner wall of the molding cavity is provided with a protrusion. When the brazing wire passes through the forming mold, the protrusion is used to form the trench. The forming method of the brazing wire includes the following steps. The brazing tube passes through the forming mold, and the trench is formed on the outer peripheral surface of the brazing tube by the protrusion.
