  • Arc wire spraying method, equipment and product
    Patent number: 10941478
    Abstract: An arc wire spraying method includes conveying at least two wires out of respective lance nozzles of a wire conveying device by means of the wire conveying device, applying current to the two wires to form an arc for melting the ends of the two wires, and applying airflow to the arc in the direction transverse to the longitudinal direction of the wire conveying device by means of an airflow applying device so as to spray the melted wire material toward a surface to be sprayed. The airflow applying device rotationally applies the airflow around the longitudinal direction of the wire conveying device. Parameters for spraying are variably adjusted along the rotating direction of the airflow applying device. The airflow is rotationally applied at a varying rotating speed.
