Are you seeking an automated solution to assess quality, reliability, and safety in your manufacturing operation? EWI recently worked with materialsIN to develop a real-time quality assurance system for ultrasonically welded, lithium-ion battery tabs. In a new paper, A Fully Automated Quality Assurance Solution for Battery Tab Welds Using Process Monitoring and AI, EWI engineers...

Integrated computational materials engineering (ICME) can be used effectively to understand thermal excursions and mechanical response in single-shot joining methods such as resistance-spot, flash-butt, friction, hot-gas, and thermite welding. As part of EWI’s ongoing series of papers examining the uses of ICME as a prediction tool in manufacturing, Senior Technology Leader Jerry Gould has written...

Auto manufacturers and suppliers need a valid, reliable way to detect flaws in electric vehicle battery enclosures, or modules. EWI has developed an inexpensive testing method with demonstrated feasibility! Our team validated an EV battery testing procedure involving colorimetric chemical reagents and a reactive gas. It’s a high-resolution marking method that’s faster and clearer than...
