Abstract: Wire arc additive manufacturing technology possesses advantages such as low cost, high efficiency, and the capacity to form large and complex structures. It has achieved extensive applications in domains like the aviation industry, shipbuilding, petrochemical engineering and medical equipment. Post processing, as a crucial part of additive manufacturing process, enhances the mechanical properties, microstructure, dimensional accuracy, and other characteristics of the additive components through further processing and treatment.The new progresses in the research of wire arc additive manufacturing and post processing technologies were reviewed, indicating that online monitoring and control, optimization of process parameters, and planning of deposition paths can improve and control the wire-arc additive manufacturing process, leading to a remarkable enhancement in the forming quality. Post-processing techniques such as heat treatment, laser shock peening, and ultrasonic impact treatment could assist to improve the comprehensive performance of the additive components. The key problems influencing the overall performance of additive components in wire-arc additive manufacturing and post processing processes were summarized, and the development trends under the influence of frontier manufacturing concepts such as big data analysis, machine learning, and digital technologies were discussed.
