The development of a high-power electron-beam welding system in South Korea marks a significant milestone in the country’s technological advancement. This breakthrough, achieved by a joint research team led by Principle Researcher Jeong Suh of the Korea Institute of Machinery and Materials (KIMM), opens the door to domestic production of a local vacuum high-power electron-beam welding system, a crucial piece of equipment for welding small modular reactors (SMRs).
SMRs, with a power capacity of 300MW or less, have been identified as a key technology in the country’s strategic plans. The successful development of this welding system not only enhances South Korea’s technological capabilities but also reduces the reliance on imported electron-beam welding devices.
The research team’s achievement in designing and manufacturing an electron gun and high-voltage device for the welding system showcases the country’s ability to overcome challenges in developing core equipment. By securing price competitiveness and improving output capabilities, the team is paving the way for the domestic production of welding systems for various applications, including SMR pressure vessels and defense industry structures.
Dr. Jeong Suh highlighted the potential of this technology in not only welding SMR pressure vessels but also large structures used in defense industries. The innovation of using local vacuum chamber technology will not only streamline the welding process but also enhance economic efficiency.
President Seog-Hyeon Ryu of KIMM emphasized the importance of this development in supporting the construction of the SMR Production Support Center, showcasing the impact of this technology on the nation’s manufacturing capabilities.
Supported by the Ministry of Trade, Industry, and Energy, this research underscores the government’s commitment to advancing manufacturing-based production systems. With this breakthrough, South Korea is poised to become a leader in electron-beam welding technology, driving innovation and economic growth in the country.
