About
Koki Yokofujita is a leading researcher in the field of laser materials processing, with a primary focus on laser peening technology and its application to improve the fatigue properties of welded metallic structures. His most notable contribution is the development of a compact, portable laser peening device, featuring a thumb-sized Nd:YAG microchip laser mounted on a collaborative robot. This innovation represents a significant leap from traditional, bulky laser systems, enabling in-situ surface treatment of large or complex components. Yokofujita’s work has demonstrated that this portable system can effectively introduce compressive residual stress into HT780 butt-welded joints, dramatically enhancing their high-cycle fatigue life. His 2022 paper on this device has already garnered 20 citations, reflecting its immediate impact on both academic research and practical industrial applications. By making laser peening more accessible and flexible, Yokofujita is helping to bridge the gap between laboratory-scale studies and real-world manufacturing and maintenance, particularly for high-strength steel structures in demanding environments.
