A method of forming an impeller for a torque converter is provided. The method includes providing an impeller shell including a back axial surface for facing away from an interior of the torque converter, providing an impeller hub including an outer circumferential surface and forming a weld joining the impeller shell and the impeller hub. The weld is contiguous with the back axial surface of the impeller shell. The weld is also contiguous with the outer circumferential surface of the impeller hub. The weld includes a root where the impeller shell and the impeller hub meet the weld. The method also includes machining the root. An impeller for a torque converter is also provided.

Method of forming a torque converter impeller including machining a weld root

A torque converter, including: a cover including: a first portion having a first surface facing at least partially in a first axial direction and a second portion extending past the first surface in the first axial direction; an impeller including: an impeller shell with a third portion: disposed radially outward of the second portion; overlapping the second portion in a radial direction such that a first line passes through the second and third portions and having a second surface: facing in a second axial direction and adjacent to and aligned with the first surface in the first axial direction such that a second line passes through the first and second surfaces; at least one blade connected to the impeller shell; and a weld fixedly securing the cover to the impeller and in contact with the first and third portions.
