Method related to joining dissimilar metals and assembly made from dissimilar metals

摘要

A method to join a first (28) and second (32) item that are made from different materials is disclosed. The method includes using a dual alloy member (36) disposed between the first (28) item and the second (32) item, the dual alloy member comprising a first material, a second material different from the first material, and a wrought region (48) between the first material and the second material. The method further includes melting together a localized area of material of the first item (28) and the first material, thereby creating a first weld joint substantially absent intermixing of the first material with the second material, and melting together a localized area of material of the second item (32) and the second material, thereby creating a second weld joint substantially absent intermixing of the second material with the first material, and thereby joining the first item (28) to the second item (32).
