Abstract: In this study, to further clarify the advantages of industrial applications of wire arc additive manufacturing (WAAM), the focus is on the repair of blades damaged by cavitation erosion using WAAM. A fan-type inducer was installed in a centrifugal pump experimental apparatus, and then paint erosion tests were conducted. Based on the tests, the fabrication time for repairing blades with a hybrid system of WAAM and machining was calculated and compared with that for fabricating a new part. It is concluded that applying WAAM to the fabrication process of an industrial turbopump has advantages not only in the manufacture of parts but also in the repair of such parts.
