Welding method and part made by the welding method

Abstract

A method for welding a first component to a second component includes providing a first component of a first alloy and having coating of a second alloy on a face of the first component, and solid state welding a second component of a third alloy to the coating of the first component. The second alloy includes only non-ferrous compounds.

Description

technical field [0001] The present disclosure relates to welding methods and parts manufactured by the welding methods. Background technique [0002] This introduction generally presents the background of the disclosure. The work of the presently named inventors is neither expressly nor implicitly acknowledged to the extent that it is described in this Introduction and to the extent that it is described in this Introduction and aspects of it that may not otherwise be considered prior art at the time of filing. is prior art for the present disclosure. [0003] In a typical motor vehicle, certain components are welded together. Some welds involve parts made of different alloys. For example, lighter alloys such as aluminum alloys or magnesium alloys can be joined to heavier alloys such as steel. Due to the differences in physical and metallurgical properties between these alloys, the joint strength may not be strong enough for some applications. Specifically, brittle inter...

AI Technical Summary

Problems solved by technology

Specifically, brittle intermetallic compound formation and high residual stresses in welded joints due to the use of alloys with different properties may limit the joint strength

[0004] These limitations may hinder and / or reduce the ability to reduce the mass of automotive components, which in turn may hinder and / or reduce fuel efficiency, economy, performance, battery life, range, and other important characteristics of the vehicle
