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...

If you are interested in EWI’s latest R&D for applied manufacturing, you can hear about it directly from our engineers throughout the month of March. EWI specialists will share new findings and applications at the following public forums and conferences over the next several weeks: LaMorte Women in Welding Virtual Conference, March 16, 2023 –...

The primary process today for robotic arc directed energy deposition (DED), used for large-scale additive manufacturing builds, is gas metal arc welding. However, two other processes, plasma-arc (PA) and gas tungsten arc (GTA) welding, have been recently studied at EWI and shown to offer greater control over power and material inputs during a build. EWI...
