SYSTEMS AND METHODS FOR TESTING INTERNAL BONDS

摘要

A transducer assembly is provided. The transducer assembly includes a magnetic portion, a body, a tensile pulse transmitter, and a pulse and current control unit. The magnetic portion is configured to provide a magnetic field. The body is disposed within an opening of the magnetic portion, and has a conductive portion configured to pass electric current near a body surface oriented toward the test surface. The tensile pulse transmitter is disposed within a cavity of the body and configured to transmit a tensile pulse into the test object. The pulse and current control unit is configured to control the tensile pulse transmitted by the tensile pulse transmitter, and to provide a current that passes through the conductive portion of the body and the test object, whereby a force urging the transducer assembly and the test object toward each other is generated responsive to the magnetic field and the current.

主权项

1. A transducer assembly configured to test an internal bond of a test object having a metallic portion corresponding to a test surface to which the transducer assembly is configured to be coupled, the transducer assembly comprising:
a magnetic portion comprising at least one magnet and configured to provide a magnetic field, the magnetic portion having an opening therein oriented toward the test surface; a conductive portion disposed within the opening of the magnetic portion; a tensile pulse transmitter configured to transmit a tensile pulse into the test object; and a pulse and current control unit coupled to the conductive portion and the tensile pulse transmitter.
