摘　　要：汽轮机叶片锻模在长期使用过程中常出现型腔表面磨损和裂纹等情况。对叶片类模具型腔的修复进行了研究。通过分析母材的焊接性,选择了焊接材料,制定了修复工艺,并付诸实施。修复后的锻模完全满足生产使用要求。该修复工艺在锻造模具生产中具有一定的指导意义。In the long-term use of turbine blade forging die, there always appears wear and crack on the surface of die cavity. The repair of the blade forging die cavity was studied. By analyzing the welding properties of base metal, the welding material was selected. The repair process was established, and it was put into practice. The forging die after repair fully meets the production＇s requirements. The reparing process has certain guiding significance in the production of forging die.
