Description

Technical Field

[0002] The task of the stern tube is to support the tail shaft or propeller shaft, and to enable the supported tail shaft or propeller shaft to pass reliably overboard, so as to prevent a large amount of overboard water from leaking into the ship and to prevent the lubricating oil from leaking out. The stern tube device is generally composed of a stern tube, a stern bearing, a sealing device, and a lubrication and cooling system.

[0003] In the process of processing the ship's tail shaft sealing device, it is often necessary to use a welding device to weld the connection parts. Since the ship's tail shaft sealing device is relatively thick, it needs to be preheated. However, the preheating is generally performed at a specified temperature. The sudden high-temperature preheating has poor temperature distribution uniformity, and due to the drastic temperature change, large thermal stress may be generated, increasing the risk of welding cracks, and the energy consumption is large. When the weld is wide, the welding head usually cannot swing back and forth during welding, resulting in a temperature difference between the inside and outside of the weld, affecting the welding effect of the weld. In the process of using the welding equipment, welding will generate high-temperature exhaust gas, which is not only easy to scald nearby personnel, but also the pollutants in the high-temperature exhaust gas will pollute the environment, and long-term inhalation will endanger personal safety.
