Joining of dissimilar materials: A review

Zheng Sun, Risto Karppi

Research output: Book/ReportReport


Multimaterial technology is set to become one of the most promising solutions for the design and fabrication of many high performance products and engineering structures. This approach is based on the efficient combined use of various materials in those places where they are most useful and economic. Joining dissimilar materials is a key process in the manufacture of multimaterial products and has hence become a very important and vital field of research and development. This report contains a literature survey on the joining of dissimilar materials. The characteristics of dissimilar material joints are discussed. Theoretical and practical problems encountered in joining dissimilar materials are reviewed with special reference to the joinability of various materials and how they can be combined. Applications of dissimilar material joints are highlighted with reference to industrial requirements. Furthermore, examples are given in order to illustrate the principles of solving specific problems. The processes used to join dissimilar materials are analyzed to show their potential, approbation and future perspectives. The survey aims at providing the industrial and R & D sectors with identification of the major needs for future development in the joining of dissimilar materials. The report gives the reader an accessible introduction to the principles of and existing information on joining dissimilar materials, and thus it is hoped to attract industries into adopting new joining techniques for solving practical problems of their own.
