Abstract
To improve the deposition efficiency and forming quality of laser fuse additive manufacturing, this paper combines the advantages of oscillating laser and double-wire additive manufacturing to realize oscillating laser double-wire additive manufacturing. The feasibility of the scheme is verified through experiments, and a corresponding three-dimensional simulation model is established. Through the comparison of experiment and simulation, the forming fit is good and the accuracy of the model is verified. Finally, the forming effects under different laser oscillating frequencies and oscillating amplitudes are studied through the simulation model. The results show that the appropriate oscillating amplitude can preheat the substrate and improve wettability. The laser oscillating frequency is inversely proportional to the forming width, and a high oscillating frequency can improve the forming effect.
