Paper: Flaw Generation in Laser Powder Bed Fusion Additive Manufacturing
To correlate data collected from monitoring and inspection techniques with actual types and sizes of discontinuities in AM components, precise flaw-generation methods need to be developed. This paper explores EWI’s work to intentionally create flaws with specific sizes and geometries using the laser powder bed fusion process.

GTAW In-process Monitoring Techniques for Electronic and Medical Device Applications
Electronic and medical device manufacturers not only require joining processes capable of producing small-scale welds of high quality, but also reliable methods of nondestructively assessing them. While real-time monitoring is well-developed for small-scale resistance welding, small-scale laser welding has no viable option. Gas tungsten arc welding (GTAW) presents an alternative welding approach with greater potential […]
