Arc Behavior in Wire Arc Additive Manufacturing Process

Procedia Manufacturing, 2020
Abstract The welding arc behavior in a wire arc additive manufacturing process was studied while building a ten-layer wall over a base plate using a cold metal transfer (CMT) power source. The real-time recorded welding current, voltage, thermal cycles at the base plate, and the synchronized high-speed arc images with each deposited layer were used ...

Residual stress and texture control in Ti-6Al-4V wire + arc additively manufactured intersections by stress relief and rolling [PDF]

, 2018
Additively manufactured intersections have the theoretical risk to contain hydrostatic tensile residual stresses, which eventually cannot be thermally stress relieved.
