摘　　要：对某发电厂2号汽轮机汽缸内壁裂纹及缸体结合面变形缺陷的焊接修复方案及其存在问题进行了探讨,并在现场实施了焊接修复。修复结果证实,采用异种钢对耐热钢铸钢件进行堆焊,可简化堆焊工艺,同时可以有效地控制基体变形,为简化耐热钢铸钢件焊接修复提供了新的有效途径和可能性,对设备的现场修复及检修具有重要意义。The weld repairing approach for internal casing crack of no. 2 turbine and joint face deformation of casing in one power plant were discussed. Weld repairing is carried out at site. Surfacing welding of heat resistance cast steel piece by special-shaped steel could simplify welding technique and effectively prevent deformation of basic structure. It provides a new and effective approach for weld repairing of heat resistance cast steel piece.
