汽车车身钣金维修 摘要：汽车钣金维修是针对汽车碰撞所产生的大小损伤进行修复的工作，即汽车车身修复。车身碰撞损伤恢复程度的好坏，将直接影响到该车修复后的使用性能和安全结构。碰撞事故车辆的修复现已不再是简单的汽车钣金的敲敲打打，修复的质量也不能单靠肉眼去观察车辆的外观缝隙，维修人员不但要了解车身的技术参数和外形尺寸，更要掌握车身材料特性，受力的特性传递车身变形趋势和受力点以及车身的生产工艺，如焊接工艺等等。在掌握这些知识的基础上，维修人员还要借助先进的测量工具，通过精准的车身三维测量，以判断车身直接的间接的受损变形情况，制定出完整的车身修复方案，配合正确的车身修复方案，将车身各关键点恢复到原有的位置。 关键词：裂纹；凹门；数据测量；车身修复 Automobile body sheet metal repair Abstract: automotive sheet metal repair is the size of damage produced in automotive collision repair work, namely the auto body repair. The degree of recovery of the body collision damage is good or bad, will directly affect the car after the restoration of the performance and safety structure. Repair has vehicle collision accidents are no longer simple automotive sheet metal by hammering, the quality of the repair can not rely solely on the human eye to observe the appearance of the vehicle gap, repair personnel not only to understand the technical parameters and the size of the body, must grasp the body material characteristics, characteristics of stress transfer body deformation and stress points and production trends process the body, such as welding etc.. Based on mastering the knowledge, repair personnel must use the advanced measurement tools, through the three-dimensional measurement of vehicle accurate, the indirect damage deformation judge body directly, make body repair scheme is complete, with the body repair scheme is correct, will return to the car body of the key points to the original location.
