Abstract

Weld deposition based Additive Manufacturing enables the capacity of fabricating fully dense components with low cost for rapid manufacturing. During the additive manufacturing of forming metal parts, the cross-sectional profile of a single weld bead is critical for improving the surface quality, dimensional accuracy. This work present the experimental study carried out to determine the best fit model to define the bead cross-section profile. The profile of the single bead was fitted by three curve functions, namely parabola, circular arc, and cosine function and the “accuracy” of the fit was determined based on regression coefficient. Both pulsed and CMT weld-deposition modes were analyzed to generate conditions for high and low penetration respectively. v
