Abstract
NiAl is preheated to a temperature between 1530.degree. C. and 1638.degree. C. causing some of the aluminum to evaporate along the faying surfaces thereby forming a glazed layer of nickel rich self-generated filler metal. The glazed faying surfaces are placed in contact, heated to 1530.degree. C. to 1570.degree. C., and pressed together to form a fusion weld.
