About
Tomoharu Kato is a leading researcher in the field of laser materials processing and structural integrity, with a primary focus on laser peening technology and its application to welded metallic components. His major contributions center on the development of compact, portable laser peening devices that introduce beneficial compressive residual stresses to improve fatigue life in high-strength steels. Kato's most cited work, "Development of a portable laser peening device and its effect on the fatigue properties of HT780 butt-welded joints" (2022, 20 citations), demonstrates a significant engineering breakthrough by miniaturizing a traditionally large-scale process into a thumb-sized Nd:YAG microchip laser mounted on a collaborative robot. This innovation makes laser peening more accessible for on-site industrial applications, particularly for extending the service life of critical welded structures. His research bridges the gap between fundamental laser-material interactions and practical, deployable solutions for fatigue enhancement. Kato's work has been recognized for its potential to transform maintenance and repair protocols in heavy industries, offering a portable, efficient alternative to conventional surface treatment methods.
