EWI recently completed a study which demonstrated the suitability of tandem/twin gas-metal arc welding for directed energy deposition (DED). Twin-wire pulsed technology offers a superior deposition rate, excellent feature fairness, and is tolerant to contact-tip-to-work variations. Because it is omni-directional with respect to travel direction and torchwire orientation, the process is compatible with robotic computer-aided...

The U.S Department of Energy (DOE) Office of Fossil Energy (FE) and the National Energy Technology Laboratory (NETL) recently selected projects to receive cost-shared R&D under the opportunity announcement (FOA) DE-FOA-0002192, Extreme Environment Materials for Power Generation. One of the projects selected is Robust Dissimilar Metal Friction Welded Spool for Enhanced Capability for Steam Power...

Robotic directed energy deposition technology offers a robust, multi-faceted process for building and repairing large-scale components. EWI is currently involved in a broad research program to mature DED technology for use in the aerospace, energy, defense, shipbuilding, and heavy manufacturing industries. As part of this effort, EWI has installed a Cloos robotic DED system for...
