The invention discloses a tower tube welding seam polishing method and device. The method comprises the following steps that a polishing device is placed above a welding seam; the direction guiding system conducts guiding and feedback, and positions the middle of a weld joint and weld toes; the excess weld metal detection system feeds back weld excess weld metal information, confirms the polishing amount and feeds back the polishing amount to the control system; the control system controls the middle grinding belt and the weld toe grinding belt to be put down and grinds the middle of the weld joint and the weld toe area in the axial direction or the circumferential direction of the tower drum, and the excess weld metal detection system conducts real-time measurement and feeds back to the control system in the grinding period; and when the control system detects that the polishing progress is equal to the measured specified value, the polishing belt stops working and is retracted.
