Abstract
A method for joining first and second axle components is provided. In one example, the method includes forming an aperture in a first axle component that is mounted to a second axle component, where the aperture has a chamfer at one end thereof, inserting an object into the aperture, and resistance welding the aperture while applying pressure to the object so that the object fills the chamfer.
Claims19
A method, comprising:
- forming an aperture in a first axle component, the first axle component mounted to a second axle component, the aperture having a chamfer on one end of the aperture;
- inserting an object into the aperture, the object sized to fit into the aperture;
- and
- resistance welding at the aperture while pressing on the object with a variable pressure, the pressure adjusted to be at a first, higher level during a first portion of the welding and then at a second, lower level during a second later portion of the welding as the object fills the chamfer.

A method, comprising:
- forming a cylindrical aperture in a first axle component, the first axle component mounted to a second axle component, the aperture having a chamfer on an end of the aperture adjacent to the second component, the chamfer having a side wall at a fixed angle relative to a central axis of the aperture;
- inserting a cylindrical slug into the aperture, the slug sized to fit into the aperture;
- and resistance welding at the aperture while pressing on the slug with a variable pressure, the pressure adjusted to be at a first, higher level during a first portion of the welding and then at a second, lower level during a second later portion of the welding as the slug fills the chamfer.
An electric axle, comprising:
- an electric drive;
- an axle having a first component and a second component joined by a slug weld formed via a slug in an aperture, the aperture having a chamfer on an end of the aperture adjacent to the second component, the chamfer having a side wall at a fixed angle relative to a central axis of the aperture, the slug filling the aperture including the chamfer.
