Abstract Scope |
Cold Metal Transfer (CMT) provides low heat input which result in minimized heat affected zone at the layer interface. Combined with a 6-axis robot arm system, it can produce stable and high deposition rate structures with single or multi-material layers. In this study, additive manufactured structures with 5000 aluminum alloy series using CMT are subjected to mechanical testing. 15cm x 10cm x 0.4cm Plate structures are build-up with combination of two different CMT arc modes with variation in heat input. The arc mode variation provided with different grain size distribution, which can affect mechanical properties. For using the residual stress after build-up, Ultrasonic Impact Treatment (UIT) process was applied to the sample surface to see the effect on mechanical stability. Tensile test and Charpy impact test were performed with Electron Backscattered Diffraction (EBSD) analysis to see the evolution of local strain and stress at the layer interface per arc mode. |
