Vacuum hot rolling joining technology andits application
Welded structures of dissimilar metals cannot be directly joined by fusion welding because of the sig-nificant difference in their material intrinsic attributes.The fabrication of dissimilar metal clad structures by vac-uum hot rolling is the best way for engineering adaptability.In this paper,the technical principle and research status of two kinds of hot-rolling joining methods including the preforming in vacuum and without vacuum are in-troduced,and the technical differences between the two methods are analyzed.It provides an effective way for the joining of dissimilar metal structures.
