DED

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...

Interested in using directed energy deposition (DED) in your operation to build fine component features or execute repairs? Laser DED can be quite expensive. However, EWI has recently developed a DED process based on gas metal arc welding (GMAW) that is significantly more cost efficient. The project is described in Reciprocating Wire Feed Gas Metal...
