Abstract

Método y dispositivo para detectar discontinuidades estructurales y uso de dicho método para el guiado de un equipo de soldadura automático. El método comprende detectar discontinuidades estructurales, mediante la detección y análisis de señales electromagnéticas obtenidas al escanear un objeto con uno o más sensores haciendo girar al sensor o sensores sobre la discontinuidad estructural, para realizar, con un mismo sensor, dos o más detecciones de diferentes zonas de la discontinuidad estructural a lo largo de la circunferencia o porción circunferencial que describe la trayectoria del sensor durante el giro. El uso del método es para el guiado de un equipo de soldadura automático. El dispositivo incluye, entre otros, un cabezal rotatorio (H) con uno o varios sensores electromagnéticos (S1-S4) a diferentes distancias radiales respecto a su eje de giro (A), unos medios de análisis para analizar las señales suministradas por los sensores (S1-S4), y unos medios de control para controlar a los diferentes elementos del dispositivo según el método de la invención.Method and device for detecting structural discontinuities and use of said method for guiding automatic welding equipment. The method comprises detecting structural discontinuities, by detecting and analyzing electromagnetic signals obtained by scanning an object with one or more sensors by rotating the sensor or sensors over the structural discontinuity, to perform, with the same sensor, two or more detections of different areas of structural discontinuity along the circumference or circumferential portion that describes the trajectory of the sensor during rotation. The use of the method is for the guidance of an automatic welding equipment. The device includes, among others, a rotating head (H) with one or more electromagnetic sensors (S1-S4) at different radial distances from its axis of rotation (A), analysis means to analyze the signals supplied by the sensors (S1-S4), and control means for controlling the different elements of the device according to the method of the invention.
