Abstract:
A method for adjustment of transducer position to compensate for ultrasonic testing beam alignment errors, the method comprising the steps of:providing a manipulator of an ultrasonic immersion testing system having a pointing direction and supporting a transducer generating an ultrasonic beam;providing a calibration body defining a target thereon;immersing the transducer of the manipulator and the calibration body in a coupling fluid in an immersion tank of the ultrasonic immersion testing system;setting the manipulator initially at a first position such that the pointing direction of the manipulator is aligned with the target of the calibration body at known coordinates; andadjusting the manipulator subsequently to a second position such that the ultrasonic beam of the transducer is brought into alignment with the target of the calibration body at the known coordinates for initiating an inspection of a test object after replacing the calibration body with the test object.
