Abstract

Un dispositif d’analyse (DA) est couplé à un appareil de soudage par résistance en courant alternatif (AS) comprenant des électrodes (E1-E2) entre lesquelles sont placées des pièces métalliques l’une contre l’autre, et un circuit d’alimentation (CA) connecté aux électrodes (E1-E2) et délivrant un courant électrique circulant entre ces dernières en traversant les pièces pour produire un point de soudure. Ce dispositif (DA) comprend un premier détecteur (D1) mesurant des premières valeurs représentatives du courant électrique, un second détecteur (D2) mesurant des secondes valeurs représentatives d’une tension entre les électrodes (E1-E2), et un analyseur (AM) analysant des évolutions temporelles des premières et secondes valeurs et délivrant un message signalant un point de soudure non conforme en cas de détection pendant sa production d’une évolution temporelle des premières valeurs supérieure à un premier seuil et d’une évolution temporelle des secondes valeurs supérieure à un second seuil. Figure à publier avec l’abrégé : Fig. 1An analysis device (DA) is coupled to an alternating current resistance welding apparatus (AS) comprising electrodes (E1-E2) between which metal parts are placed against each other, and a circuit for supply (AC) connected to the electrodes (E1-E2) and delivering an electric current circulating between the latter passing through the parts to produce a spot weld. This device (DA) comprises a first detector (D1) measuring first values representative of the electric current, a second detector (D2) measuring second values representative of a voltage between the electrodes (E1-E2), and an analyzer (AM ) analyzing temporal evolutions of the first and second values and delivering a message indicating a non-compliant welding point in the event of detection during its production of a temporal evolution of the first values greater than a first threshold and of a temporal evolution of the second values greater than a second threshold. Figure to be published with abstract: Fig. 1
