Abstract
A unit for a turbocharger can include a turbine wheel portion that includes a turbine wheel material and a turbine wheel axis; a shaft portion that includes a shaft material and a shaft axis; a first weld that includes a first average axial position over a first azimuthal span and first weld composition formed of a greater proportion of the turbine wheel material than the shaft material; and a second weld that includes a second average axial position over a second azimuthal span and second weld composition formed of a greater proportion of the turbine wheel material than the shaft material, where a sum of the first azimuthal span and the second azimuthal span is approximately 360 degrees, where the first average axial position differs from the second average axial position, and where the first weld composition differs from the second weld composition.
