Journal Article
Dryburgh, P., Pieris, D., Martina, F., Patel, R., Sharples, S., Li, W., …Smith, R. J. (2019). Spatially resolved acoustic spectroscopy for integrity assessment in wire–arc additive manufacturing. Additive Manufacturing, 28, 236-251. https://doi.org/10.1016/j.addma.2019.04.015

Wire-arc additive manufacturing (WAAM) is an emergent method for the production and repair of high value components. Introduction of plastic strain by inter-pass rolling has been shown to produce grain refinement and improve mechanical properties, ho...
