摘要
Dissimilar 6061 aluminum alloy and copper were friction-stir welded with various tool rotations and welding speeds to achieve a void free weld zone. We could not acquire the joint without void by changing the tool rotation and welding speed. However, a sound joint of the friction-stir welded dissimilar Cu/6061 At alloy without voids was finally achieved by shifting the tool insertion location, where it deviated from the centerline of the two materials. The weld zone produced a very complex structure mixed with a dynamic recrystallized structure of each material, intermetallic compound and unpredictable oxides. These compounds in the weld zone were formed by the chemical reaction and the absorption of oxygen during the welding process.
