Thermal cutting processes that can be applied to dismantling nuclear power plants include oxygen cutting, plasma cutting, and laser cutting. According to the global trend, research projects are being carried out in various countries to upgrade laser cutting, and many studies are also being conducted in Korea with plans to apply laser cutting processes when dismantling nuclear power plants. However, with the current technology level of the laser cutting process, the maximum thickness that can be cut is limited to 250 mm. Therefore, in this study, a laser-oxygen hybrid cutting process was implemented by adding a laser heat source to the oxygen cutting process that can cut carbon steel with a thickness of 250 mm or more (RV, beam, column, beam, etc.) when dismantling the nuclear power plant. This has the advantage of improving the cutting speed and reducing the cutting width Kerf compared to conventional oxygen cutting. In this research, the laser-oxygen hybrid cutting process consisted of laser cutting to which Raycus’ 8 kW Fiber Laser power source was applied and oxygen cutting to which hydrogen was applied with Fuel Gas. The oxygen torch was placed perpendicular to the test piece, and the laser head was irradiated by tilting 35° to 70°. The effects of cutting directions on quality and performance were studied, and cutting paths were selected by comparing cutting results. Thereafter, it was confirmed that there is an optimal laser output power according to the cutting thickness by studying the effect on the cutting surface quality by changing only the laser output power under the same cutting conditions. The results of this study are expected to be helpful in the remote cutting process using laser-oxygen hybrid cutting when dismantling domestic nuclear power plants in the future.

도법으로 풀어내는 매체 특징을 가진 전각예술은 중국 서화와 구별될 뿐만 아니라 문화 속성을 가지고 있기에 다른 문화 속 새김 예술들과 차이가 나므로 전각의 주요한 형식 요소로 간주 된다. 현대 문화 속에서, 전각에서의 칼이 자아내는 미적 의미는 중국예술전통을 계승함과 동시에 현대전각의 품평과 평가 기준에 새로운 의미를 부여했다. 중국의 고대 시품을 기본 형식으로 삼아 당대 정신에 부합하는 미적 계보와 체계적 틀 구축은 그 의의가 매우 중대하다고 본다. 이를 위해 본 논문에서는 원형에 맞는 우아미 등의 평가 기준과 근거로 4가지 미적 유형을 제안한다.
