| Research Abstract |
The objectives of this research are clarification of fundamental phenomena and development of smart process in ultra-high-power-density fiber laser welding. As for the fundamental clarification, the laser absorption of SUS304 stainless steel achieved 80% and the absorption mechanism was revealed on the basis of X-ray high-speed pictures of the keyhole. With respect to smart process, laser adaptive control applied for continuous-wave fiber laser welding. Consideration of thermal storage effects led to success of stable sound welds at acceleration or deceleration in welding speed.
