Redistribution of residual stress state by lateral rolling of components produced by wire plus arc additive manufacture (WAAM)

Abstract: Wire + Arc Additive Manufacturing (WAAM) is a digital tool less manufacturing technique that uses traditional arc welding power sources and a robotic system, to build large three-dimensional metallic components and structures. This manufacturing tool provides high recovery of deposition as opposed to traditional subtractive machining. However, the thermal stress generated during such process would remain locked-in as self-balancing residual stress and would result in distortion of the component which would depend on the geometry and dimension of the component. Rolling, as means of local mechanical tensioning, could be an effective way to remove such localised stress and subsequently the distortion will be eliminated. The present proposal would investigate the effectiveness of lateral rolling process and roller geometry in redistributing the stress field and eliminating distortion.
