摘　　要：钢制车身的CO_2气体保护焊修复方法已在汽车维修企业得到了广泛应用。针对修复过程中产生的气孔、烧穿、咬边、焊瘤、飞溅、焊缝成形不良以及焊接变形过大等焊接缺陷,从操作人员、工艺、设备、材料和环境等影响缺陷形成的主要因素进行了全面分析,对各种具体缺陷提出了详细的控制措施。The C02 gas shielded arc welding repairing method of steel vehicle body has been widely used in automobile maintenance enterprises. Aiming at defects produced in the process such as air cavity, bumthrough, undercut, welding flash, spatter, poor welding formation and too big welding deformation, the main factors affecting the defect formation were analyzed comprehensively flom aspects of operators, process, equipment, materials and environment, and control measures were put forward for various defects.
