Region of Research
This research chair has been developing welding technology to realize international competitive manufacturing for wide range of thick-plate structures by fusing advanced technologies owned by JWRI and Hitachi Zosen Co. It aims to realize smart welding factory.
The high power laser technology for thick plate welding developed in this chair has reached a practical level at the factory. Now, we are developing the foundation of the digital welding technology required at next generation like process simulation technology and waveform controlled the high heat input digital submerged arc welding technology.
