Influence of deposit track on the forming and performance of wire arc additive manufactured 2319 aluminum alloy components

ABSTRACT

The wire arc additive manufacturing (WAAM) method has a high material utilization rate and is superior to the casting method. However, the higher the dimensional accuracy required for additive manufacturing components and the more complex the components are, the more difficult it is to guarantee their quality. The subsequent processing requires a large amount of labour cost. In this study, a track optimization method is proposed to achieve the quality control of 2319 aluminium alloy additive manufacturing components, which can improve the forming accuracy and optimize the component performance. The experimental results show that multi-track stacking can effectively reduce the heat accumulation in the deposition process. The component forming accuracy is improved by about 70%, the tensile strength by about 6% and the yield strength by about 15%. The influence of deposition track on the forming accuracy and quality of WAAM components has rarely been studied.
