Wire as a feedstock referred to as Wire Arc Additive Manufacturing for Additive Manufacturing purposes has been investigated since the 1990s. The advantages of WAAM mainly are the high deposition rates, the freedom of geometry with a high dimensional accuracy and potentially low delivery times. Due to these facts, WAAM is gaining technical and economic relevance, but needs to be investigated to benefit to its advantages in comparison to conventional component manufacturing. Based on the inevitable heat input during WAAM, the knowledge of the impact on the distortion and residual stress state is essential. In this master thesis, this impact of a WAAMed flange on a decanter centrifuge¿s cylindrical bowl out of 1.4362 and 1.4462 is investigated by destructive and non-destructive measurements. In addition, mechanical properties and the microstructure of the used materials are characterized by tensile testing, hardness mappings, light optical and stereo microscope investigations. Finally, the performed WAAM process is assessed in terms of economic operation as an alternative to the conventional centrifugal casting manufacturing process. These investigations showed that the cylindrical bowl is plastically deformed in the area of the WAAMed flange and elastic deformation also occurs up to much greater distances.
