Background

In order to ensure the performance of a welded joint and reduce welding defects in the welding process of the nickel-based alloy pressure container, the temperature between layers needs to be kept low, but the heat input amount of welding is very large in the product welding process, so that the heat is not diffused, and the temperature at the welded joint is too high. The welding process needs to be stopped to cool the control layer temperature, and the welding speed is seriously affected. In this case, technological measures are required to accelerate the cooling rate of the weld joint to ensure the welding efficiency. The conventional mode for accelerating the cooling speed of the welding seam is an air cooling mode and a water cooling mode, but through experiments and production practices of the company, the cooling effect of the air cooling and the performance of the welding joint of the welding seam of the air cooling are not as good as the water cooling effect, so that the welding of the nickel-based alloy adopts a water cooling mode, and the water cooling mode is that a hand-held water pipe is aligned with the welding seam for spraying in the welding process, because the water cooling time is longer after the welding, the mode of spraying the hand-held water pipe has the defect of labor saving, and the spraying range of the pure water pipe is not concentrated at the welding seam, and the corresponding water collecting device is also lacking.
