  • FLEXIBLE EDDY CURRENT PROBE
    Publication number: 20160025682
    Abstract: A flexible eddy current probe and a method of use are provided. A flexible eddy current probe (300) includes at least one substantially planar eddy current array (304) capable of measuring an electromagnetic condition of a portion of a test object (202), wherein the at least one eddy current array (304) is disposed on a flexible substrate (316), and wherein the flexible substrate (316) is conformable to a portion of the test object (202). The flexible eddy current probe includes at least one elongated electrical conductor (312) capable of electrically connecting the at least one eddy current array (304) to a test instrument, and a glove (402) capable of being fitted to an operator's hand and capable of carrying the eddy current array (304) and conforming the array in testing communication with the test object (202).

  • Apparatus and method for ultrasonically examining remotely located welds in cast stainless steel nuclear steam supply systems
    Patent number: 6449326
    Abstract: An apparatus for ultrasonically examining a weld in a nuclear steam supply system includes an elongated guide rod for positioning within a pipe of the nuclear steam supply system. An ultrasonic transducer is positioned at an end of the elongated guide rod. A collapsible shoe encloses the ultrasonic transducer. The collapsible shoe includes a biasing mechanism to allow the collapsible shoe to pass through the pipe while the pipe is at a first circumference and while the pipe is at a second circumference. The collapsible shoe continuously contacts the pipe to establish ultrasonic coupling for the ultrasonic transducer.
