Region of Research

 Fundamental studies are performed concerning joining, cutting, surface modification and removal processing with laser beams, aimed at advanced fusion between laser science and production engineering. We focus on clarification of welding or joining mechanisms and intelligent monitoring technology on the basis of the visualization of material processing phenomena with high-speed optical observation or X-ray transmission imaging techniques. Moreover, laser should be utilized with not only high thermal efficiency but also physicochemical effects induced by interaction between light and material. Thus we create innovative processes including laser direct joining of metal and plastic, put these processes to practical use and disseminate achievements of our research to the world.

Current Research Subjects

  • Development and evaluation of joining and welding processes for the advanced functional materials.
  • Elucidation of laser welding phenomena and imperfection formation mechanisms and development of remedies.
  • Fundamental studies on laser interaction with materials and fundamental studies of materials processing utilizing laser.
  • Creation of new function by surface modification with laser.
