A dissimilar metal article comprising:
- a first metallic component comprising a first metallic component first end surface;
- a second metallic component comprising a second metallic component first end surface;
- an additive flow material bonded to each of the first metallic component first end surface and the second metallic component first end surface;
- wherein the additive flow material intermixes with the first metallic component and the second metallic component;
- and
- the additive flow material forms a collar around the first metallic component and the second metallic component at a position radially outward from the first metallic component and the second metallic component.
