Abstract: The invention relates to a method and apparatus for monitoring the quality of weld spots produced by resistance spot welding according to which a weld spot which has just been made is observed by means of a video camera sensitive to infrared radiation at a well determined instant of its cooling, with a view to comparing it with a reference weld spot observed previously under the same conditions; the value and passage of the welding current is controlled by means of the video signal and the synchronization signals coming from said camera, which signals are exploited to make an image reconnaissance by counting scanning lines or dots defined along the lines by a clock, when this video signal becomes greater than an electrical voltage representative of the level of emission of infrared radiation of the periphery of the reference weld spot.
