摘　　要：材质为ZG35Cr1Mo的挤压模座在精加工过程中出现裂纹。采用补焊方式进行修复。在修复过程中,通过对工艺设计、预热温度、层间温度、回火温度、焊接参数进行研究,制定出焊接工艺,最终使产品通过各项检验。The extrusion die holder which material is ZG35Cr1Mo has cracks in the finishing process. Welding methods are applied for repairing. The process design,preheating temperature,interpass temperature,tempering temperature,welding parameters are determined to establish a welding process and make products meet various test requirements.
