Laser and Hybrid Technologies for Surface Engineering and Welding
暫譯: 表面工程與焊接的激光與混合技術

Igor Krivtsun is the director of the E.O. Paton Electric Welding Institute and an eminent Ukrainian physicist specializing in gas discharge physics and welding process theory. He has authored over 310 scientific publications and holds 17 patents. His research focuses on the interaction between low-temperature technological plasmas (like welding arcs and plasma jets) and materials during arc, plasma, laser, and hybrid processing. His pioneering work in hybrid laser-arc welding has earned international recognition and led to the development of foundational principles for laser-arc plasma torches. Under his leadership, this expertise has resulted in innovative processes like laser-microplasma welding, laser-plasma powder surfacing, and the deposition of diamond-like coatings.

Leonid Golovko is a professor at the National Technical University of Ukraine 'Igor Sikorsky Kyiv Polytechnic Institute' (KPI). As one of the founders of the scientific school of laser technologies at KPI in the 1970s, he headed the Department of Laser Engineering and Physical Technologies for nearly 20 years. His scientific activity has resulted in 356 publications, including 15 monographs (some republished internationally), and over 150 Ukrainian patents. His research involves studying physicochemical processes in materials under concentrated energy flows to create new materials and highly efficient processing technologies.

Serhii Fomichov is a professor at the Institute of Materials Science and Welding at NTUU 'Igor Sikorsky KPI', director of an IIW/EWF Approved Training Body, and chairman of the Safeguarding Impartiality Committee of Bureau Veritas Ukraine. He has nearly five decades of experience in non-destructive testing (NDT) and condition monitoring for critical infrastructure like pipelines and pressure vessels, where he developed equipment and national standards. For over a decade, he has also focused on surface engineering using nano-sized powders to improve the wear resistance of equipment in the mining and transport industries.

Oleksii Kaglyak heads the Department of Laser Systems and Advance Technology at NTUU 'Igor Sikorsky KPI'. His scientific work is centered on laser surface technology, with a focus on forming shielding materials, sintering instrumental composites with diamond or cubic boron nitride, and laser-assisted formation of bimetallic materials. Dr. Kaglyak has published 40 scientific works, including one monograph and six patents.

Yevgenia Chvertko is an associate professor at the Institute of Materials Science and Welding at NTUU 'Igor Sikorsky KPI' and a member of the Board of Directors of the International Institute of Welding (IIW). With over two decades of teaching experience at KPI, she instructs on pressure welding, quality control, and welding coordination. For more than 15 years, she has been a key figure in training and qualifying welding personnel according to IIW guidelines. As a member of IIW and ISO working groups, she co-authored Ukraine's national standard for welder training, harmonizing it with international requirements.

伊戈爾·克里夫茨恩（Igor Krivtsun）是E.O.帕頓電焊研究所的所長，也是專注於氣體放電物理和焊接過程理論的著名烏克蘭物理學家。他已發表超過310篇科學出版物並擁有17項專利。他的研究重點在於低溫技術等離子體（如焊接弧和等離子體噴流）與材料在弧焊、等離子體、激光和混合加工過程中的相互作用。他在混合激光-弧焊方面的開創性工作獲得了國際認可，並促成了激光-弧等離子體火炬的基礎原則的發展。在他的領導下，這一專業知識促成了激光微等離子體焊接、激光等離子體粉末表面處理和類金剛石塗層沉積等創新工藝的出現。

列昂尼德·戈洛夫科（Leonid Golovko）是烏克蘭國立技術大學「伊戈爾·西科爾斯基基輔理工學院」（KPI）的教授。作為1970年代KPI激光技術科學學派的創始人之一，他在激光工程與物理技術系任職近20年。他的科學活動產生了356篇出版物，包括15本專著（部分在國際上再版）和超過150項烏克蘭專利。他的研究涉及在集中能量流下研究材料中的物理化學過程，以創造新材料和高效加工技術。

謝爾希·福米喬夫（Serhii Fomichov）是NTUU「伊戈爾·西科爾斯基KPI」材料科學與焊接研究所的教授，IIW/EWF認可培訓機構的主任，以及烏克蘭必維（Bureau Veritas Ukraine）公正性保障委員會的主席。他在無損檢測（NDT）和關鍵基礎設施（如管道和壓力容器）的狀態監測方面擁有近五十年的經驗，並在此領域開發了設備和國家標準。十多年來，他還專注於使用納米級粉末進行表面工程，以提高礦業和運輸行業設備的耐磨性。

奧列克西·卡格利亞克（Oleksii Kaglyak）是NTUU「伊戈爾·西科爾斯基KPI」激光系統與先進技術系的主任。他的科學工作集中在激光表面技術上，重點是形成屏蔽材料、燒結含有金剛石或立方氮化硼的工具複合材料，以及激光輔助形成雙金屬材料。卡格利亞克博士已發表40篇科學著作，包括一本專著和六項專利。

葉夫根尼亞·切維爾科（Yevgenia Chvertko）是NTUU「伊戈爾·西科爾斯基KPI」材料科學與焊接研究所的副教授，也是國際焊接學會（IIW）董事會成員。她在KPI擁有超過20年的教學經驗，教授壓力焊接、質量控制和焊接協調。15年來，她一直是根據IIW指導方針培訓和資格認證焊接人員的關鍵人物。作為IIW和ISO工作組的成員，她共同編寫了烏克蘭的焊工培訓國家標準，並使其與國際要求保持一致。
