Advancing Polymer Weld Analysis to Prevent Fatigue Failures  At EWI, we always strive to solve the most pressing manufacturing challenges. We’re excited to announce the launch of a groundbreaking research initiative that focuses on a critical issue in polymer welding — identifying the relationship between intermolecular diffusion and fatigue failures using Heated After Cross-Section (HACS)...

Our country’s ability to manufacture large structures and systems has decreased over the last several decades. In response to cross-industry concerns, NIST recently sponsored a project led by EWI and its partners to develop a U.S. Roadmap for Accelerating Production of Large Structures and Systems. The findings of this study can be found in NIST...

Welding thick parts efficiently and effectively is a huge challenge in heavy industry. The extra steps that manufacturers need to take to ensure quality can be costly and time-consuming – not to mention the possibility of introducing other problems like distortion and waste. EWI has developed and tested several new methods that are now being...
