초록

Recently, in the automobile industry, the development of technology that can satisfy environmental regulations and fuel economy reduction requirements due to vehicle weight is an important topic. To solve this issue, vehicle-body weight reduction technology is a promising solution. To reduce the vehicle weight, automobiles with a large amount of aluminum use general wire welding (MIG, TIG) to bond aluminum components to each other. However, for complex three-dimensional shapes and dissimilar materials, traditional welding methods of inducing metal bonding and joining access are difficult to implement. Therefore, in such cases, joining techniques should be used. In this study, the mechanical properties of clinching joints without rivets are studied among various mechanical joint methods for weight reduction.


Keywords: Hybrid clinching joint, Dissimilar material, Aluminum alloy, Interlock
