| Abstract: | Pinion of No. 3 pulverizing mill of No. 1 boiler in Xiangtan Power Plant was fractured during operation. It was decided to repair it with welding in order to operate as soon as possible. Based on the analysis of pinion welding properties, Ni-base welding rod which is dissimilar with base metal was put forward for repairment, special welding procedure was established to repair on site which was proved to be effective and provided valuable experience for oth- er power plants to solve similar problem. |
