摘要： A method for forming a clad structure utilizing a moving resistance energy source. The method forms a metallurgical bond between a cladding layer and a primary layer such that at least 2% of a cladding layer surface is metallurgically fusion bonded to a primary layer surface. The fusion bond does not extend all the way through the primary layer or the cladding layer. Either, or both, of the layers may incorporate surface texturing to reduce the contact area between the layers, and melting point suppressants may be incorporated into the method.
