摘要：In a spot joining method and apparatus, pressing force of a rotating tool ismaintained at a first pressing force, the frictional heat due to the rotation of the rotating

tool is generated on a surface of an aluminum plate, and the aluminum plate is softenedby this frictional heat, so as to ensure the centering of a pin portion of the rotating tool.Thus, even if the pin of the rotating tool is short, a stable joining position can be obtained,so that the aluminum material can be prevented from accumulating on the rotating tool,the appearance of joining surfaces can be prevented from deteriorating, and thesufficient joining strength can be obtained.
