China Deploys First Intelligent Welding System for Ultra-Deep Vertical Shafts at Songyang Pumped Storage Power Station
Overview
On November 3, according to CCTV reporting cited by IT Home, the Three Gorges Group confirmed the deployment of China's first complete set of intelligent welding equipment for ultra-deep vertical shafts at the Songyang Pumped Storage Power Station in Zhejiang. Designed for extreme deep-earth conditions, the system automates high-strength steel pipe welding in a 637-meter-deep shaft with only about 45 centimeters of available width. The equipment features robotic welders, 5G control, and laser tracking, achieving a welding speed of 30 to 50 centimeters per minute, which is over 65% faster than manual welding, with a first-pass pass rate of 99%. This marks progress in China's autonomous development of ultra-deep underground engineering equipment.
