Abstract

Abstract A method for lining workpieces with dissimilar foils using shot peening is proposed. The foil is welded to the surface of the workpiece due to plastic deformation caused by the hit of many shots. To examine the possibility of welding, point welding using a single shot is performed, and the bond strength is evaluated by tearing the foil from the workpiece. In this experiment, the workpieces are mild steel, commercially pure copper and aluminium, and the foils are commercially pure aluminium and mild steel of 0.1 mm thickness. The lining of the soft metal with the hard metal and the reverse combination are dealt with. The weldability is also heightened by heating the foil and workpiece. By means of peening with many shots, the aluminum foil is successfully welded over the surface of the mild steel workpiece.
