    Abstract: Systems and methods form induction rotors by performing isostatic pressing (HIP) to weld clad to a shaft, which allows for scaling the manufacturing of solid steel rotors, as compared to conventional techniques. In examples, the rotors are designed for high-speed motors and may include recessed short circuit rings and/or end rings. An exemplary process molds an alloy powder into cladding such that heretofore unachievable rotor designs are achievable according to systems and methods described herein. In examples, a thin source-layer is introduced to welding zones, thereby enriching and strengthening the resulting joint at welding zones. The source-layer may be introduced by adding an intermediate layer comprising the source material between the materials being welded. The reduced alloy-depletion welding disclosed herein strengthens the welding area joints and provides for the manufacture of component designs, which were previously unachievable due to alloy-depletion weaknesses and environmental constraints.
