Resistance welds on overlapped sheets of metal, such as the welded side seam of 3 piece cans, are monitored by measuring the width of the extrusion (5, 6) formed by material flowing out from the edge of the overlapped sheets (1, 2) caused by the welding process. The width of the extrusion (5, 6) is interpreted in terms of the temperature of the weld, and the welding process can be adjusted accordingly. The measurement of the extrusion width can be done optically.
On contrôle des soudures par résistance sur des feuilles de métal se chevauchant l'une par rapport à l'autre, tel que le joint latéral soudé de boîtes métalliques en trois pièces, par mesure de la largeur de l'extrusion (5, 6) qui s'est créée sous l'effet de l'écoulement du matériau depuis le bord desdites feuilles (1, 2) provoqué par l'opération de soudage. On interprète la largeur de l'extrusion (5, 6) en termes de température de la soudure, ce qui permet de régler l'opération de soudage. On peut effectuer optiquement la mesure de la largeur de l'extrusion.
