Abstract
Advanced cryogenic machinery such as present-generation 5 MVA superconducting generator prototypes[1,2] contain welded rotor components that experience high rotational stresses at extreme cryogenic temperatures to 4.2 K. To ensure achievement of a reliable failure-safe design of such components, adequate characterization of weldments in specific materials of processed and fabricated conditions representative of those considered for employment in final fabricated hardware must be accomplished.
