Claim 9:
10. The method for detecting a surface welding quality of friction stir welding according to claim 7, wherein when only the flatness of the front reference region is less than the threshold, an average height of the front reference region is calculated as the flash reference height; when only the flatness of the rear reference region is less than the threshold, an average height of the rear reference region is calculated as the flash reference height; when the flatness of the front reference region and the flatness of the rear reference region are both less than the threshold, an average height of the front reference region and the rear reference region is calculated as the flash reference height; when the flatness of the front reference region and the flatness of the rear reference region are both greater than the threshold, the latest reference height calculated previously is taken as the flash reference height.
