Abstract Wire and Arc Additive Manufacturing (WAAM) technology has the advantages of high-efficiency and low-cost to fabricate large-scaled components with medium-complexity. 2319 aluminum alloy is a widely used in aerospace and military industries. Problems of porosity, residual stress, distortion, and poor mechanical properties were focused on in this paper. The mechanism of defect formation during fabrication and strengthening mechanism of peening process were investigated. In order to learn the droplet transfer and molten pool flow behavior, CFD models of molten pools for the pulse mode of CMT (CMT + P) and pulse reverse polarity CMT mode… More >
