Power transmission towers serve as the backbone of the power transmission grid, bearing the vital responsibility of safely and reliably delivering electricity from power plants to countless households. Each towering structure acts as a crucial cornerstone supporting the functioning of society, economic development, and the stability of people's livelihoods. As the construction of new power systems accelerates and ultra-high voltage (UHV) and extra-high voltage (EHV) transmission lines continue to expand, increasingly stringent demands are being placed on the structural strength, durability, and construction efficiency of these towers.

The tower foot serves as the critical load-bearing connection point between the steel tower and its foundation, directly withstanding complex stresses such as the tower's own weight, wind loads, and conductor tension. Recently, SIASUN and Chongqing Yanhai Technology Co., Ltd. (hereinafter referred to as "Yanhai Technology") joined forces to overcome technical bottlenecks in the intelligent welding of critical-grade tower foot seams, jointly ushering in a new era of intelligent welding for power transmission tower feet.
