Abstract: The process parameters directly impact the forming quality of components produced by wire laser oscillating additive manufacturing. To explore the optimal process parameters for single-track deposition of TC11 titanium alloy, the influence of process parameters on single-track deposition formation and deposition quality was studied. By conducting range analysis on the comprehensive evaluation indicator of TC11 single-track deposition quality, the process parameters were optimized. The results show that increasing the laser power or decreasing the scanning speed both lead to an increase in the deposition width and penetration depth. The wire feed speed mainly affects the deposition height, and there is a positive correlation between the two. The degree of influence of each orthogonal test factor on deposition quality, from greatest to least, is laser power, wire feed speed, and scanning speed. Among them, laser power has the most significant impact on deposition quality. With the optimal laser oscillation parameters, the best process parameters for single-track deposition are a laser power of 1000 W, a scanning speed of 0.4 m/min, and a wire feed speed of 1.0 m/min.
