| Abstract: | Discharge sand steel pipes of Three Gorges right bank underground power plant is made from compound steel plate of stainless steel. Welding quality requirement is high, and welding difficulty is big. According site practice, some typical welding defects produced easily in the practice were pointed out, and cause of produced defects was analyzed. Based on analysis of structure, environment and technology measures of prevention welding defects were proposed, and welding quality of steel pipe was guaranteed. |
