ABSTRACT:
Method and apparatus for ultrasonic flaw inspection of non-rotating tubular goods. The apparatus includes a test head with circumferential arrays of transducers oriented for inspection for each of transverse, longitudinal and wall thickness defects, and the test head includes individual pulser and pre-amplifier arrays as sequentially controlled from a remotely disposed operator console. The console includes sequential signal processing circuitry for developing and displaying defect indications for the test specimen as it is moved longitudinally through the test head.
