Claim 10:
11. A method of forming a valve body having an area of dissimilar material fused therein, the method comprising:
obtaining a valve core, the valve core having a first core part and a second core part split from the first core part, the first core part configured to define a fluid inlet of a valve body and the second core part configured to define a fluid outlet of the valve body;
placing a ring made of a first material between the first core part and the second core part;
joining the first core part and the second core part together to form the valve core with the ring;
placing the valve core in a casting pattern;
filling the casting pattern with a second material to form the valve body, the valve body comprising the fluid inlet and the fluid outlet;
fusing the ring with the valve body during the filling of the casting pattern by partially melting the ring, thereby allowing the first material to fuse with the second material;
cooling the second material; and
removing the valve core,
wherein the first core part includes a first alignment structure and the second core part includes a second alignment structure that engages the first alignment structure when the first core part and the second core part are joined together.
