[0002] Water conservancy projects are ambitious projects designed to control and allocate natural surface and groundwater resources. Their fundamental goal is to eliminate harm and promote benefits, providing solid support for the development and progress of human society. To achieve this goal, water conservancy projects require the construction of various hydraulic structures, such as dams, dikes, spillways, sluice gates, water inlets, channels, ferries, rafts, and fishways. These structures play a vital role in water conservancy projects.
[0003] However, pipe welding is an essential step in the construction of existing water conservancy projects.
