1 reports · 1 sources
China's first complete set of intelligent welding equipment dedicated to pressure steel pipes in ultra-deep shafts has been officially put into use at the Songyang Pumped Storage Power Station in Zhejiang, as disclosed by China Three Gorges Corporation. The equipment was independently developed for the extreme working conditions of narrow deep shafts in deep-earth engineering, and is equipped with an outer circumferential seam welding robot and an inner circumferential seam automatic horizontal welding machine. China Three Gorges Corporation states that the equipment can achieve welding speeds of 30 to 50 centimeters per minute, with efficiency improved by more than 65% compared with traditional manual welding, and a one-time weld pass rate of 99%. These efficiency and pass-rate figures all come from China Three Gorges Corporation's statements.
