This paper investigates welding-induced residual stresses in wind power towers and their critical influence on structural stability and fatigue strength. Various methods for mitigating welding residual stress and enhancing fatigue performance are examined. The study analyzes the underlying principles and effectiveness of key stress relief techniques, including heat treatment and vibration aging. In addition, approaches to improving fatigue strength—such as the optimization of welding processes and refinement of structural design—are elaborated. The findings are intended to serve as a reference for ensuring the reliable operation of wind power towers.
