A system and method of determining the quality of a spot weld based on a set of image data includes separating the weld data from the background data and estimating a diameter of a weld (e.g., the nugget diameter of a spot weld) based on the weld data. The image data (e.g., a digital image) represents an image of the weld and includes weld data and background data. The estimation indicates the quality of the weld. In one embodiment, the surface brightness of the image data attributable to the spot weld is used to estimate the inner diameter of the spot weld.
