Effect of parameters on friction stir welding joint of 7075Al and AZ31BMg

The friction effect of welding parameters such as welding speed, rotating frequency and material location on the stir welding joints of 7075Al and AZ31BMg were analyzed. The results show that the good welding joint is obtained when the rotating frequency is 13 rad/s and the welding speed is 30 mm/min. Besides, in order to obtain no defect welding joint, 7075Al should be set on back side, the pin should be clockwise and offset to Al or Mg side.
