  • Patent number: 11826827
    Abstract: A coaxial powder-feeding nozzle includes a partition wall-type shell, a powder flow area, a cooling liquid flow area and a shielding gas conveying channel. A powder self-cleaning filter is on the outer side of the partition wall-type shell; the powder self-cleaning filter includes a set of powder collecting tubes on each side of the partition wall-type shell in the axial direction; each set of powder collecting tubes includes at least one powder collecting tube; under the coaction of a suction force applied by a powder collecting system and the self-weight of residual powder, a residual powder inlet of each powder collecting tube causes the residual powder on the opposite side to roll down to the bottom along the wall surface of a metal tube to be processed on the same side, and to be gathered at the front end of the residual powder inlet of the powder collecting tube.
