Abstract
A method for manufacturing a torque converter shell is provided to induce favorable residual stress in a direction of a loading condition to improve durability during cycle pressurization. The method includes inducing favorable residual stress on a front cover, an impeller shell, or both the front cover and the impeller shell to improve the durability of these components. The induced residual stresses reduce the stress experienced by these components during operation. The front cover and impeller shell are welded together to form the torque converter shell.
