| Abstract: | Aluminum foams(AF) is a novel material with structural and functional properties. Taking full advantages of aluminum foams, AFS is often combined with dense metal to improve the comprehensive mechanical properties and reduce cost, the obtained structure is named sandwich. There are lots of connection means for sandwich structure, but welding is the most reliable way to connect AFS. In this paper, the characteristics of aluminum foams and welding problems are introduced, the welding methods including conventional arc welding, laser welding, brazing, diffusion welding, friction stir welding, plasma arc welding and ultrasonic welding are reviewed.The limitations of each process are discussed, and finally the development direction of the welding process is analyzed. |
