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 manufacturing software.
This work is discussed in High Deposition GMA Technology for Large-scale Additive Manufacturing, a paper by EWI associates Dennis Harwig and Michael Carney.
