Exploration and Application of Sheet Metal Technology on Pit Package Repairing

Abstract

Automobile body always bumps, resulting in a large number of pit package damage to happen, which caused adverse impacts on production. The sheet metal repairing technology were used in automobile maintenance. The theoretical basis, common methods and tools for repairing were described at first. Then procedures and standards of repairing were studied. Based on the properties of materials and the basic knowledge of mechanics, the automobile door was repaired. Experiments showed that the repaired method is good, and the repaired doors met quality standards. Practices proved that the technology were applied to other parts of automobile body, and it achieved great economic and social benefits, also.
