Rotating array probe system for non-destructive testing
First Claim
1. An inspection system for performing non-destructive testing of test object, the inspection system comprising:
- a test object conveyor for conveying the test object along a longitudinal conveyance path;
at least one probe assembly further including at least one phased-array probe, the phased-array probe being configured to send ultrasonic beams to the test object and to sense echo signals induced in the test object and convert the echoes to electronic response data and a probe assembly conveyor configured to movably support the probe assembly, to move the probe assembly on a circumferential path about the test object;
at least one data acquisition unit disposed on the probe assembly conveyor which acquires the response data from the phased-array probe, provides phased array firing command to the phased-array probe in order to apply desired focus angles for the ultrasonic beams for the testing and perform a first part of data processing including producing real-time A-scan data;
a control and data processing system coupled to the test object conveyor and to the probe assembly conveyor and the data acquisition unit, the processing system configured to send command to the data acquisition unit, receive and provide a second part of data processing received from the data acquisition unit while, simultaneously while the test object moves along the longitudinal path and the phased-array probes move on the circumferential path.

Abstract
A device is disclosed for performing non-destructive inspection and testing (NDT/NDI) of an elongated test object, wherein the inspection system includes: a test object conveyor for conveying the test object along a longitudinal conveyance path; a probe assembly including phased-array probes, the probe assembly being configured to induce signals in the test object and sense echoes reflected from the test object; a probe assembly conveyor configured to movably support the probe assembly, to move the probe assembly on a circumferential path about the test object; and a control system coupled to the test object conveyor and to the probe assembly conveyor and configured to allow data acquisition by and from the phased-array probes while, simultaneously, the test object moves along the longitudinal path and the phased-array probes move on the circumferential path. The test system may include phased-array probes of different types to optimize detecting faults or cracks in the test object which extend in different directions.
