- Abstract
In this paper, the 304 stainless steel components were fabricated on a low carbon steel with thickness about 20 mm by using MIG arc additive manufacturing technology. The surface quality and the distribution characteristic of residual stress of the components prepared with three different arc additive manufacturing strategies were studied. In addition, the typical microstructures in different characteristic zones of components were revealed. The results showed that the macro features of the component with one single way strategy was highest at the initial, then it exhibited flat morphology with moderate height, and the height was lowest at the end part. However, the components with the other two strategies presented higher height at the middle parts and lower height at both ends. Specially, the maximum stress (~399.4 MPa) obtained at the onset of the component with one single way strategy. It was found that the ideal strategy with low stress could be obtained by fabricating with different strategies in adjacent layers.The typical microstructures were composed of columnar grain at the bottom, dendrite in the middle, and equiaxed grain at the top of the components.
