ABSTRACT:
The invention relates to a device for the automatic checking of welds between tubular parts. A carriage comprises two fixed ends with their centering wheels, a movable mechanism with two flanges and guide rails. This mechanism rotates on bearings. The carriage includes a drum moving over rails and bearing a telescopic arm orientable by rotation on its axis. The end of the arm carries an inspection head. Digital control ensures the programming of the movement and the orientation of the inspection head opposite the weld. The device and method are useful for the ultrasonic checking of the welds of the nodes of offshore platforms and for the checking of welds in nuclear power systems.
