学术报告摘要：Wire Arc Additive Manufacturing (WAAM) is an advanced metal 3D printing technology that offers high deposition rates, cost-effectiveness, and flexibility for producing large-scale components. However, challenges such as process stability, material integrity, and quality control hinder its widespread adoption. Digital Twinning (DT) has emerged as a powerful tool to enhance WAAM by creating a virtual replica of the physical process, enabling real-time monitoring, predictive analysis, and optimization. This presentation explores the application of DT in WAAM, highlighting its role in process simulation, defect prediction, and adaptive control. By integrating sensor data, machine learning, and computational models, DT facilitates intelligent decision-making, reducing defects and improving part quality. The study also discusses the challenges in implementing DT for WAAM, including data accuracy, computational demands, and integration with existing manufacturing systems. The findings suggest that DT has the potential to revolutionize WAAM by enabling smart manufacturing, reducing material waste, and enhancing production efficiency.
