Wire Arc Additive Manufacturing
Printing marine-grade metal with an industrial robot
I automate metal deposition on an ABB IRB 2600ID and study how process parameters and external vibration set the microstructure and residual stress of marine alloys — nickel aluminum bronze, the metal ship propellers are cast in, and Inconel 625. Measuring that stress means getting inside the bulk of the part: I was awarded 2026 neutron scattering beam time at Oak Ridge National Laboratory's High Flux Isotope Reactor to characterize it.
