Recently, the problem of battery weight in electric vehicles has emerged. In order to to achieve weight reduction of the vehicle body, it is necessary to replace the material and optimize the design accordingly, and the actual situation is that an efficient product manufacturing method is required to change the lightweight material. In this study, a spot welding test was performed on aluminum.

Recently, the trend in architectural forms has been toward taller and larger building. The building materials, therefore, are getting larger and heavier as wall. Most of the construction projects are, however, dependent on outdated equipment and human resources. Construction processes up to now face a number of problems, including dangerous work, high construction cost and heterogeneous construction quality. In various construction sites, automation in construction has been introduced to address these problems. This paper proposes a human-machine cooperative system in the construction site; the system utilizes construction of a curtain wall in tall buildings. The use of automation system at construction sites can reduce the need of human involvement. Construction time and cost can be reduced as well. The most important aspect of the use of automation system at construction sites is prevention of accidents.
