Complex builds make wire arc additive manufacturing (WAAM) difficult to control the uniformity of deposit shapes and sizes. Here we develop, test and combine a three-dimensional heat transfer and fluid flow model of WAAM with corresponding experiment
Wire and arc additive remanufacturing (WAAR) technology has become a new solution for hot-forging dies repair and remanufacturing. In this study, a path generation method is proposed for WAAR of hot-forging dies. At first, a WAAR process of the hot-f
