Abstract
A method of welding two dissimilar metals of substantially different melting temperatures by passing an electric current through an interface created by biasing a projection located on the higher melting point metal into intimate contact with a surface located on the lower melting point material. The electrical current substantially liquifies a portion of only the second metal so that the projection is not substantially deformed by the welding operation.
