Every steel structure has a complicated combination of free curved surfaces, in order to attain the desired structural performance and appearance. In manufacturing such shell paltes, mechanical bending or heat-bending process has been used. The heat-bending process features the use of simple equipment and can be used to form a variety of shapes which other methods cannot. On the other hand, there is one inherent problem that it requires well skilled technical workers with a lot of experience. Such workers are difficult to train in order to require many experience, and recently there has been the want of workers in the job of heat-bending process. To cope with this problem and to develop the automatic systems of steel plate-bending process by heating with improved efficiency, we had investigated the opinions and suggestions of engineers working in ship-yards and had summarized their comments. At the same time, we had conducted heat-bending tests to investigate the distortion behavior of steel paltes by heating. Based on the results of the opinion survey and the experiments, this report presents an outline of our approach to automation and improved efficiency of the steel plate-bending process by heating.
