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。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.
