Abstract
A method to evaluate the integrity of spot welds includes one or more of the following: projecting light from a light source at a spot weld to illuminate the spot weld; capturing an image of the illuminated spot weld with a camera; transmitting information about the image of the illuminated spot weld to a central processing unit (CPU); and evaluating with the CPU the information about the image of the illuminated spot weld coupled with an artificial intelligence neural networked-based algorithm to determine the integrity of the spot weld in real time.
