Abstract Scope |
Melt pools generated during additive manufacturing (AM) dictate the resulting structure of printed parts. As AM techniques increase in accessibility, a lack of fundamental understanding of melt pools has increased the need for real-time monitoring techniques to isolate critical mechanisms that drive unwanted material properties, i.e., pores or resulting microstructure. Current methods utilizing optical or thermal imaging only provide a 2D view of the melt pool, whereas ultrasonic testing can offer a low-cost, 3D response in real-time. In this project, experiments performed using high-speed synchrotron X-ray imaging with ultrasonic inspection were conducted in real-time on melt pools generated in Al 6061 samples. The ultrasonic response was validated using the X-ray images as ground truth with critical melt pool features, such as depth and solidification rates, extracted accurately. |
