the surfacing spray device is fixed on surfacing equipment through a tool, the relative position of the jet orifice 21 of the nozzle 2 and the welding gun 500 is kept unchanged, the surfacing pipe 400 rotates relatively and moves axially, cold water enters the three-way pipe 1 from the water inlet branch pipe 11 of the three-way pipe 1, compressed air enters the three-way pipe 1 from the air inlet branch pipe 12 of the three-way pipe 1, when the cold water is sprayed out from the tangential outlet end of the water outlet nozzle 5, the compressed air sprayed out by the air nozzle 6 is blown away, so that the cold water is mixed with the air, a high-pressure steam-water mixture is formed in the extension pipe 4, and finally the cold water is sprayed out to the position of the surfacing pipe 400 opposite to the welding gun 500 through the jet orifice 21 of the nozzle 2, so that the position of a molten pool achieves the effect of accelerating cooling and solidification.
The infrared temperature measuring head 301 of the temperature detection feedback module detects the temperature of the welding position of the surfacing pipe 400 and feeds back the temperature to the control module, and the control module adjusts the cold water supply amount of the cold water supply device 100 according to the feedback result of the infrared temperature measuring head 301, so that the water content in atomized water vapor is changed, and the cooling speed is controlled by changing the heat conductivity of the atomized water vapor.
