ABSTRACT
Sidenor Industrial has manufactured six very big Lower Shafts for the Three Gorges Hydraulic Power Plant in the Yangtze River at the Yichang dam in China. As it is known, this will be the biggest hydropower station all over the world as the performance of each generator set will be 840 MW. The main challenges for SIDENOR have been Forging and welding such big components as well as machining very large diameters (4120 mm). All manufacturing operations, whose detailed fabrication processes are shown along the paper, were carried out at SIDENOR REINOSA Works.
Key words: Hydroelectric generation, big pieces forging, welding of very thick parts.
