Abstract
Pure copper plate C1100 and aluminum 1050 plate were joined by friction stir welding. The influence of the tool offset on the macrostructure and the strength of the joints were explored. At various tool offsets, the tunnel defects seemed to be in-avoidable. However, at the high offsets, the tunnel size is small. The tunnel size is increased with the reduction of the tool offset. The tensile and bending strength reached to a highest value at a welding regime with the tool offset around 3.0 mm. The strength bonding between copper and aluminum could be obtained about 80% of the base aluminum 1050.
