Abstract Scope |
Additive manufacturing is an innovative technology that produces parts layer by layer using different feedstock, including powder and wire. Current AM techniques mainly focus on powder bed processes with disadvantages such as high powder cost and limited size of components. Wire arc additive manufacturing (WAAM) overcomes these issues since it permits the economical production of medium- to large-scale parts with relatively high deposition rates. This study investigates the effect of triple weld beads on the microstructure of low-carbon steel, ER70S-6. Detailed microstructural analyses, including grain size measurements, phase analysis, x-ray diffraction analysis, and microhardness tests, were conducted. The optical and scanning electron microscopy images revealed variations in microstructure along the build direction and also within single melt pools, presumably attributed to differences in cooling rates along the build direction and within melt pools. |
