Patent

CA 2322531

The testing of weld seams obtained by laser welding of a butt joint poses considerable difficulties. According to the invention, to detect welding defects the weld seam length is scanned continuously along the weld seam and welding defects are detected on the basis of excessively raised areas of the weld seam.

Le contrôle de cordons de soudures obtenus par soudage au laser de pièces assemblées bout à bout présente de grandes difficultés. Pour remédier à ce problème, l'invention est caractérisée en ce que, pour la détection des défauts de soudage, la hauteur du cordon de soudure est balayée en continu le long du cordon de soudure et les défauts de soudage sont détectés en fonction des zones surélevées que présente ledit cordon.
