Patent ID: 11656205

Abstract:
A method and arrangement for testing and/or correction of a weld (34, 36, 38) of a test object (26, 102), including alignment of an ultrasonic probe (16, 128) guided by a robot (100) on a target position of the weld (28, 30, 32), determination of the actual position (34, 36, 38) of the weld by means of an optical sensor (22, 130) and alignment of the ultrasonic probe (16) on the actual position, and measurement of the weld, where CAD data of the target position of the weld (28, 30, 32) is made available, on the basis of the CAD data of the weld the ultrasonic probe (16, 128) is aligned on the target position of the weld, and the ultrasonic probe is placed on the weld with controlled force after determination of the actual position (34, 36, 38) of the weld by means of the optical sensor (22, 130).
