This thesis investigates the optimization of the hot wire laser additive manufacturing (HWLAM) process with a focus on Inconel 718 deposition. HWLAM is a wire-based directed energy deposition technique that combines laser power with resistive wire preheating to improve energy efficiency and deposition stability. Compared to conventional wire laser additive manufacturing (WLAM), the introduction of current as an additional process parameter significantly affects heat input, material flow, and final part quality. In this study, four key process parameters (laser power, current, scanning speed, and wire feeding speed) were systematically examined to evaluate their influence on bead geometry, overall surface quality, and microstructural characteristics.
