Abstract

In a method for attaching a first casting core to a second casting core, a first portion of the first casting core is brought into engagement or close proximity with a second portion of the second casting core. The first and second portions are dipped in a ceramic slurry to form a coating around the first and second portions. The coating is hardened to form a joint between the first and second portions.
