Ultrasonic metal welding (UMW) is widely used in high-volume manufacturing, particularly lithium-ion battery assembly, due to its fast cycle time and ability to join thin or dissimilar materials. But the process is sensitive to variations in tooling, materials, and process conditions, and conventional quality control relies on destructive testing methods that are costly, time-consuming, and...

Data-based tools and techniques can significantly improve manufacturing efficiency and productivity. To date, however, there have been challenges – both real and perceived – to full-scale adoption of data science across industrial sectors. To address these obstacles, EWI Director of Data Science Alex Kitt has written Data Science: New Approaches to Address Manufacturing Challenges. This...

Integrated computational materials engineering (ICME) principles can be applied to model thermo-mechanical material behavior in joining and additive manufacturing applications. Demonstrations and examples have been presented in several recent EWI publications.* The ICME framework can also offer a solution approach to modeling microstructural response in similar applications. EWI Principal Engineer Michael Eff and Senior Technology...
