Igor Krivtsun is a Professor, Director of the E.O. Paton Electric Welding Institute of the National Academy of Sciences of Ukraine. He is a noted scientist in the field of gas discharge physics and theory of welding processes. He made a prominent contribution to development of the above research areas. His basic studies are dedicated to investigation of the physical phenomena occurring in the low-temperature technological plasma (welding arcs, plasma jets, optical and other types of gas discharge), as well as processes of interaction of the electric arc plasma and laser radiation with a material treated under conditions of arc, plasma, laser and hybrid welding, surfacing and coating. His research interest includes hybrid laser-plasma processes of welding and materials treatment. He worked out the theory of interaction of the focused laser beam and arc plasma with the condensed media, which made it possible to describe from the common standpoints the processes of the arc (plasma), laser and combined laser-plasma effects on compact and dispersed materials. Prof. Krivtsun is a full member of the National Academy of Sciences of Ukraine, and a member of the ASM International. He actively cooperates with various R&D institutions of different countries, regularly presents scientific reports at prestigious national and international conferences and participates in accomplishment of a number of international research projects. He is the Editor-in-Chief of the Paton Welding Journal. He has more than 300 scientific publications, including 5 monographs and 18 patents. Fuad Khoshnaw is a senior academic and researcher at the School of Engineering and Sustainable Development at De Montfort University in the United Kingdom, where he has served as a senior lecturer since joining in 2018.
