| Abstract: | The electric spark build-up welding technology features less heat input and negligible residual stress etc.,which is non- repla- ceable in the welding of special key components.This paper introduces the electric spark build-up welding technology,used to repair and restore successfully the worn groove marks on the journal of main shaft of100MWsteam turbine in one Lanzhou power plant,the eroded groove marks on the sealing surface of steam turbine casing in one Shandong power plant and the worn surface of main shaft of circulating pump in the heat network of one Taiyuan power plant.The practices show that the electric spark build-up welding technology has great application prospect in the repair and restoration of key components(such as shafts)in power industry. |
