A torque converter is provided. The torque converter includes a front cover. The front cover includes a radially extending section and an axially extending section extending axially from an outer radial end of the radially extending section. The torque converter also includes a rear cover. The rear cover includes a rear radially extending section and a rear axially extending section extending axially from an outer radial end of the rear radially extending section. The torque converter also includes a plurality of baffles connected to the front cover. Each of the baffles includes a first tab connected to the axially extending section of the front cover. A method of forming a torque converter is also provided.

Respective outer peripheral surfaces (33, 35) of opening-side end portions (30, 31) of a front cover (12) and a pump shell (7), which have been shaped by pressing, are formed by slimming such that the outside diameters of the slimmed outer peripheral surfaces are equal to each other. With the opening-side end portions abutting against each other, a high-energy beam such as a laser beam (R) is radiated toward the abutment surfaces (30, 31) from the radially outer side to weld the abutment surfaces to each other. Consequently, it is possible to perform welding accurately through easy processing in order to easily manufacture a fluid coupling with high precision that facilitates post-processing.

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.

A torque converter is provided. The torque converter includes an impeller; a turbine axially movable toward and away from the impeller; and a damper coupled to the turbine, the damper including an elastic element forcing the turbine against the impeller in an equal pressure condition. A method of forming a torque converter is also provided. The method includes forming a damper to include an elastic element; providing the damper inside a front cover so the damper contacts the front cover; and providing axially movable turbine between the damper and an impeller such that the elastic element forces the turbine to engage an impeller in an equal pressure condition.

A torque converter turbine is provided. The torque converter turbine includes a plurality of blades, an annular bowl shaped blade supporting portion supporting the blades and a mass fixed to the blade supporting portion. A method of forming a torque converter turbine is also provided. The method includes providing a blade supporting portion of a turbine shell with mass and connecting a plurality of blades to the blade supporting portion.
