COMPOSITIONS AND METHODS FOR DISSIMILAR MATERIAL WELDING

摘要

Devices and methods of welding dissimilar materials are contemplated in w hich an adaptor is used in an intermediate position between the dissimilar m aterials. Most preferred adaptors are manufactured by friction stir welding from two dissimilar materials that are identical or similar to the dissimila r materials to be welded together. Therefore, coupling of dissimilar materia ls in the field via the adaptors is greatly simplified as conventional weldi ng methods can now be employed.
