Information × Registration Number 0125U000985, R & D request Title Research into the patterns of interaction between a plasma arc and fiber laser radiation with the surface of the welded metal, the conditions for the emergence of a synergistic effect and its influence on the formation of welded joints Head Korzhyk Volodymyr M., д.т.н. Registration Date 08-02-2025 Organization E.O. Paton Electric Welding Institute (PWI) popup.description1 To investigate the features of steels and aluminum alloys and the influence of the parameters of the focused laser beam and compressed arc on the efficiency of heat transfer from the hybrid laser-plasma energy source to the welded metal. To identify the conditions for the formation of a synergistic effect and the parameters of the regimes of its stable existence. To establish the patterns of the influence of the hybrid energy source on the course of physical and metallurgical processes, the features of structure formation, the formation of a stressed-deformed state and the physical and mechanical properties of welded joints of alloyed steels and aluminum alloys. To conduct analytical and monitoring studies of promising areas of development of hybrid laser-plasma technologies within the framework of Ukraine's integration into the European Research Area, including in the conditions of post-war reconstruction of Ukraine. popup.nrat_date 2025-02-08 Close
