Abstract
Welded assemblies and related methods of making the welded assemblies include a first component of a first metal material, a second component of a second metal material that is different from the first metal material, and a transition material including one or more of a high entropy alloy, a pure element, and an alloy that is not a high entropy alloy, and that is arranged between and contacting the first component and the second component. An ultrasonic weld joins the transition material to the first component, and a fusion weld joins the first component to the second component. The fusion weld contact the first component, the second component, and the transition material. The amount or level of one or more of galvanic corrosion, intermetallic compounds, and solidification cracking in the fusion weld is less than if the first component was fusion welded directly to the second component.
