摘　　要：分析了某汽轮机高压内缸裂纹产生的原因,介绍了消缺方案和焊前坡口面处理措施,制定了合理的补焊工艺方案和控制变形措施,最终裂纹一次返修合格。The cause of crack of high pressure inner casing for steam turbine has been analyzed. Then the defect elimination plan and the treatment measures for groove surface before repair welding have been introduced. Meanwhile, the reasonable repair welding process and the deformation controlling measures have been prepared. Eventually, the product meets the requirements after the crack repair welding for the first time.
