The first efforts to use ultrasonic testing to detect flaws in solid material occurred in the 1930s. [1] On May 27, 1940, U.S. researcher Dr. Floyd Firestone of the University of Michigan applies for a U.S. invention patent for the first practical ultrasonic testing method.
If the material contains a crack or flaw which make the spatial distribution of the electrical conductivity nonuniform, the path of the eddy currents is perturbed and the impedance of the coil which generates the AC magnetic field is modified. By measuring the impedance of this coil, a crack can hence be detected.
Controlled Unclassified Information (CUI) is a category of unclassified information within the U.S. Federal government. The CUI program was created by President Obama’s Executive Order 13556 to create a streamlined method for information sharing and safeguarding.
The dead zone is approximately 5 mm and there is no flaw detection in this zone. Calibration blocks with side drilled holes as shown in Reference [4] and ISO 10863 used to validate the "dead zone" and sizing accuracy.
