Due to the lag in temperature detection, non-uniform temperature distribution across various parts of components, and differences in phase transition temperatures among different materials, using the overall phase transition temperature of the repaired component as the boundary temperature for controlling component deformation still leads to significant thermal deformation. This paper explores the application of the golden ratio division method to phase transition temperature and utilizes this temperature as the control temperature for additive manufacturing. Based on this temperature, the entire additive manufacturing process is designed and experimentally verified. The experimental results demonstrate that the additive manufacturing process controlled by this temperature can significantly reduce deformation, enhance the quality of the workpiece, and reduce subsequent machining requirements.
