Theoretical investigation of roll bonding process of clad sheets by finite element method

Roll bonding is a solid-state welding process to join similar and dissimilar metals and a well-established and widely used manufacturing process. In this study the rolling process of St12/Al1050 clad strips were simulated by finite element methods (FEM). Effects of various parameters such as the total thickness reduction of strip and friction coefficient in roll-sheet interface upon the bonding behaviour and deformation of each sheet were also studied. The validity of FEM results were verified according to experimental investigations that showed satisfactory consistency with experimental results.
