<p>Electron beam deposition coating offers excellent performance and quality; however, its optimization is highly dependent on the operator, leading to significant uncertainty. Numerous experiments are required to optimize the process based on the characteristics of the equipment and materials. In this study, a new electron beam pattern w</p><p>as proposed for rapid optimization and quantitative control of the electron beam deposition process, and a study was conducted to stably melt the ingot. This pattern was designed to be applied to commonly used round rod-shaped ingots, and by using two variables, it was possible to simulate various energy distributions while making the control simple. In addition, experimental verification was performed to melt the ingot using the proposed pattern, and the physical phenomena associated with the ingot's melting behavior were systematically analyzed.</p>
