Directed Energy Deposition (Page 2)

This past September, EWI was awarded a $17 million, 3-year contract with the U.S. Air Force to develop convergent manufacturing (CM) platforms for maintenance, repair, and overhaul (MRO) sustainment. The project is now being managed under the auspices of the Air Force Research Laboratory (AFRL). Technical development work is already taking place at EWI’s labs...

EWI’s Green Laser Capability for Electrification, Copper Welding, and DED By Jacob Hay The use of industrial lasers for manufacturing has been gaining popularity for decades as laser sources have improved in efficiency and reliability. A properly selected laser energy source combined with the right system can offer great flexibility, providing varying energy densities, wavelengths, and...

Precise control of the wire electrode or “tool-point” position is critical in gas metal arc welding and arc directed energy deposition. Newly developed elliptical wire technology (EWT) offers improvements in tool-point control. Recently, EWI completed a study of EWT, comparing many of its features against standard round-wire electrode feedstock. The promising results are discussed in...
