## Summary

China's first intelligent welding equipment set dedicated to pressure steel pipes in ultra-deep vertical shafts has officially entered service at the Songyang Pumped Storage Power Station in Zhejiang, according to China Three Gorges Corporation. The equipment is equipped with an outer circumferential seam welding robot and an inner circumferential seam automatic horizontal welding machine, and features 5G control, laser weld seam tracking, and a welding expert database, enabling it to automatically identify weld seam positions and match welding parameters. Welding speed reaches 30 to 50 centimeters per minute, efficiency is more than 65% higher than traditional manual welding, and the one-time pass rate for weld seams is 99%.
