Abstract
A method for making a torque converter includes the steps of forming a blade having a tab extending outward from the blade and along a portion of a length of the blade. A recess is formed in the housing sized to receive the first tab. The recess defines an edge adjacent the tab and extending along the tab. The tab is inserted within the recess to form a housing assembly. A brazing material is provided between the tab and the housing. The assembly is positioned within a magnetic heating machine and magnetically heated

A method for making a torque converter comprising the steps of:
- forming a blade having a first tab extending outward from the blade and along a portion of a length of the blade;
- forming a recess in a housing sized to receive the first tab therein, the recess defining an edge adjacent the first tab and extending along the first tab;
- inserting the first tab within the recess to form a housing assembly;
- positioning the housing assembly within a magnetic heating machine;
- providing brazing material between the first tab and the housing;
- and
- magnetically heating the first tab and the housing at the recess.
A method for making a bladed torque converter having a housing carrying multiple blades, comprising the steps of:
- forming a blade having multiple tabs extending outwardly from the blade and spaced from adjacent tabs around the periphery of the blade, each blade having a first tab extending along a portion of the length of the blade;
- forming a plurality of recesses in the housing aligned in at least two rows, each row spaced from an adjacent row about a longitudinal axis of the torque converter, each recess of a row being located and sized to receive a corresponding tab therein, at least one recess of each row defining an edge adjacent the corresponding tab and extending along the tab;
- inserting the tabs within the corresponding recesses, thereby forming a housing assembly;
- positioning the housing assembly within a magnetic heating machine;
- clamping the housing assembly to the magnetic heating machine;
- providing a brazing material between each of the tabs and the housing;
- and
- activating the magnetic heating machine to kinetically heat the brazing material to braze the tabs to the housing.
