Patent ID: 8291766

Claim:
A method for ultrasonic testing of a workpiece, the method which comprises: launching a multiplicity of ultrasonic testing pulses into the workpiece from a test surface thereof, and thereby launching at least two of the ultrasonic testing pulses into the workpiece to be tested at launching points spaced apart from one another by a given test step width measured along the test surface; placing an ultrasonic test head on the test surface and generating the testing pulses with the test head, and selecting the test step width to be smaller than a lateral position resolution prescribed by a design of the ultrasonic test head and operating parameters thereof during the ultrasonic testing process; receiving signals representing measured values from the workpiece in response to the at least two ultrasonic testing pulses; and calculating a single measured value (Ī) assigned to a local point in the workpiece on a basis of the received signals associated with and received in response to the at least two ultrasonic testing pulses.
