1. In terms of fishery farming, marine floating balls play a role in fixing and marking the farming areas. Farmers connect the floating balls into a net to demarcate exclusive farming areas, which can not only prevent farmed organisms from escaping, but also facilitate management and harvesting. At the same time, the floating balls can also serve as navigation marks for ships sailing at sea, reminding passing ships to avoid the farming areas and prevent damage to the farming facilities.

2. In addition, in offshore engineering construction, marine floating balls can be used to locate and support offshore platforms, pipelines and other facilities. When laying subsea pipelines, the floating balls can assist in the laying and positioning of the pipelines to ensure that the pipelines are laid accurately along the预定 route. In some large - scale offshore wind power projects, the floating balls can also provide necessary support and guarantee for the installation and maintenance of the wind turbine foundations.

3. The surface of vibration - friction welding is flat and smooth, with no obvious welding marks visible, which improves the aesthetics of the floating balls. In terms of performance, the welded floating balls have excellent sealing and water resistance, and can work stably for a long time in a complex marine environment. For example, in sea areas with strong winds and waves, the floating balls welded by vibration - friction welding can effectively resist the impact and erosion of seawater, maintain good buoyancy and stability, and ensure the normal operation of the equipped equipment. At the same time, due to the high welding strength, the welded parts of the floating balls are not easy to crack or be damaged when subjected to external collisions, improving the reliability and safety of the floating balls.
