[0002] The main objective of wind turbine fairing welding fixture design is to improve welding efficiency and quality, while ensuring welding accuracy and stability. Wind turbine fairing welding fixtures typically include positioning structures, such as the positioning component body, contact limiting components, and top-connecting limiting components. These structures enable precise positioning of the workpiece, thereby ensuring welding accuracy and quality.

[0003] Existing wind turbine fairings are typically placed on a workbench and externally fixed on both sides during welding. This method of fixing affects the space and obstructs the welding process, requiring changes to the clamping points. This is time-consuming, labor-intensive, and inconvenient. Furthermore, the welding of wind turbine fairings is done manually with a handheld welding gun. Since most of the welding positions on wind turbine fairings are curved, the quality of manual welding is poor, and the workload is heavy, severely impacting the efficiency of wind turbine fairing welding.
