Friction stir welding has been attempted to evaluate joint strength of lap joint between aluminium sheet (AA6063) and zinc-coated steel (HIF-GA) sheet under diff-erent combination of rotational speed and traverse speed. The shear strength decreases significantly when rotational speed increases from 700 to 1,500 rpm at a traverse speed of 30 mm/min. At traverse speed of 50mm/min, increasing rotational speed from 700 to 1,500 rpm. Essentially, higher fracture load of the lap joint is obtained within a certain range of energy. The results have been correlated with the microstructural characteristics at the bond interface using energy despersive X-ray spectroscopy, ele-ctron probe micro analyzer, and X-ray diffraction. The results show that characteristics of intermetallic comp-ound formed at the interface derived from energy input takes predominating role towards lap joint of Al and coated steel. Furthermore, force and torque responses influenced by the processing parameters can be utilized as weld quality check.
