In the fabrication of alumina-based multilayer ceramics sintering shrinkages with lamination conditions such as lamination pressure temperature and laminating with and without press die were compared. The sintering shrinkage was affected substantially by lamination pressure and temperature and in the case of laminatino without press die the lower laminated density and a large difference in shrinkage with direction were observed. These results can be explained by introducing a new factor which is the ratio of the changes of areas before and after lamination.

The technology of Laser lamination joining of silicon steel sheets has been studied in this paper. Conventional sheets lamination process does not meet the requirments for the improvement electric parts performance. In response to this, a new Laser spot joining method has been developed. This study performs the Laser spot lamination joining while synchronizing the sillicon steel sheets in the dies with the press movement. Several conclusions have been drawn in this paper. Effects of beam focus, power, atmosphere gas and press oil etc.
