Abstract
Studied the relative motion between friction stir and welding board of different parameters through high-speed photography, and also analyzed the metal flow during friction stir welding combined appearance of microstructure with transverse cross section and board. It could be divided into two stages which were platform stage and traverse stage in one periodical which equaled to the time that stir rotated one circle spent. In platform stage the function of stir pin was heating the front metal. As the result of this function formed specified thickness layer of visco-plastic metal. In feed stage the visco-plastic metal. In feed stage the visco-plastic front metal was carried integrally by stir pin.
