Ultrasound testing principle
The ultrasonic principle is based on the fact that solid materials are good conductors of sound waves. Whereby the waves are not only reflected at the interfaces but also by internal flaws (material separations, inclusions etc.). The interaction effect of sound waves with the material is stronger the smaller the wave length, this means the higher the frequency of the wave.
c = Sound velocity [km/s]
f = Frequency [MHz]
r= Wave lenght [mm]
ultrasonic flaw detector is a new generation digital controlled A-pulse ultrasonic multi-channel flaw detector. The instrument is widely applied to the automatic or semi-automatic non-destructive ultrasonic testing of titanium tube, zirconium tubes, and book-walled pipe, seamless steel tubes, welded gas and oil pipelines, nonferrous metals, ferrous metals and some non-metallic pipes, rods, plates and railway rails and other shaped workpieces.

Eddy current testing principle
In standard eddy current testing, a circular coil carrying an AC current is placed in close proximity to an electrically conductive specimen. The alternating current in the coil generates a changing magnetic field, which interacts with the test object and induces eddy currents. Variations in the phase and magnitude of these eddy currents can be monitored using a second 'search' coil, or by measuring changes to the current flowing in the primary 'excitation' coil. Variations in the electrical conductivity or magnetic permeability of the test object, or the presence of any flaws, will cause a change in eddy current flow and a corresponding change in the phase and amplitude of the measured current. This is the basis of standard (flat coil) eddy current inspection, the most widely used eddy current technique.
