[0002] Girth welding has many advantages, which have made it widely used in industrial production. The following are the main benefits of girth welding: Fast welding speed: Girth welding can achieve fast and continuous welding operations, which can greatly improve work efficiency compared with manual welding. Automated girth welding equipment can monitor and adjust welding parameters in real time to ensure the quality and consistency of the weld, thereby improving the overall welding quality. Uniform and beautiful welds: Girth welding can form uniform and beautiful welds, reducing the possibility of weld defects. Simple and convenient operation: Girth welding equipment is usually designed with a simple and easy-to-use operation interface, supporting one-button operation, reducing the difficulty of operation and labor intensity. Girth welding technology is suitable for a variety of materials and structures, such as petrochemical, shipbuilding, water supply pipelines, oil and gas pipelines and other fields. Due to the high degree of automation, labor costs are reduced, and the consumption of welding materials is also saved. Automated welding reduces the safety hazards of manual welding and improves the safety of the production process. The thermal deformation during girth welding is small, which helps to maintain the dimensional accuracy of the workpiece. Automated girth welding equipment can perform continuous and high-speed welding operations, significantly improving production efficiency.

The staff first places the submersible pump casing to be processed on the top of the fixed plate, and then starts the driving motor. The driving motor rotates to drive the active gear to rotate. The active gear rotates and drives the driven gear to rotate through the transmission track. The driven gear rotates to drive the first screw rod to rotate, thereby driving the clamping plates on the outer surface of the first screw rod to move toward each other.

[0015] 3) The submersible pump casing annular seam welding equipment is provided with a coolant spraying device. After welding is completed, the staff starts the first water pump, and the first water pump sucks the coolant in the storage tank into the spiral hose, and then starts the rotating motor. The rotation of the rotating motor drives the third screw to rotate, thereby driving the moving seat to slide, thereby driving the spiral hose to slide, and then starts the electric push rod to push the liquid storage tube to the vicinity of the casing to be processed, and then the coolant in the liquid storage tube is sprayed out through the spray head to cool the welded casing.
