摘　　要：针对某型动车组牵引变流器7003高强铝合金柜体裙边安装座的腐蚀裂纹,采用交直流TIG焊机进行返修焊接。通过设计返修工艺流程、制定返修工艺方案、选用返修焊接填充材料和焊接设备、制作返修焊接试件并判定试件焊接质量、分析确定焊接参数,形成了完整的返修焊接工艺,确保批量返修焊接质量及产品的使用寿命和可靠性。According to the corrosion crack of 7003 high strength aluminium alloy cabinet skirt mounting seat for the EMU traction converter, this paper adopts AC and DC TIG machine to complete repair welding. Rework process and rework process plan are designed. Rework welding consumable and rework welding equipment are selected. Rework welded specimen is produced for analyzing the welding quality and welding parameters. A complete repair welding process is formed to ensure service life and reliability of the mass producing goods.
