Formation of SUS304/Aluminum Alloys Using Wire and Arc Additive Manufacturing

Abstract: In this study, wire and arc additive manufacturing (WAAM) was used to form SUS304/aluminum alloys. The buildup wall was well shaped using a pulse current consisting of a base current of 150 A and peak current of 200 A and a 0.2 m/min travel speed. Metallographic observation revealed that the original grains were columnar grains and transformed into equiaxed grains in the top area. The increased content of alloying elements in the fused layer improved the hardness of the buildup wall. The buildup wall formed us… Show more

“…However, Wang et al [42] and Panchenko et al [43] held opposing views, claiming that faster welding rates were favored to optimize production efficiencies and product quality. Hao et al [44] also found that columnar grains expanded around the fusing line and converted into equiaxed grains towards the top of the build-up wall, decreasing grain size as travel speed increased. Arc length correction (ALC) was also important in bead geometry development [45].…”

“…The principle of WAAM is different from the other additive manufacturing methods that were previously described, and few papers regarding the corrosion study of WAAMprepared SS have been published. Hao et al used WAAM to prepare SUS304, and studied a difference with the corrosion behavior depending on the types of applied current in the WAAM, which included a pulse current and a constant current [65]. It was indicated that the samples with a pulse current showed better corrosion resistance than the samples with a constant current.…”
