Ultrasonic Inspection

ULTRASONIC INSPECTION
The propagation and transmission of ultra-high frequency sound waves through a test specimen and evaluating the reflected sound waves on a time delay oscilloscope. This phenomenon of sound vibration is not only applicable to solids, but gases and liquids as well.

ULTRASONIC TESTING METHODS
We have numerous units and methods for evaluating internal integrity. Below are only a few of the ways we can explore your materials, in order to find sub-surface discontinuities.

We currently utilize a number of different ultrasonic generating and inspection equipment, based upon the pulse/echo system. A description of this method would be as follows: short pulses of ultrasonic energy are generated electronically and transmitted through the test material by contract, or through a liquid couplant (immersion). The pulses are reflected from the opposite side and any discountinuities within the piece appear as blips on the Cathode Ray Screen.

TYPICAL APPLICATIONS
Structural weldments, ship hull thickness, corrosion surveys, weld quality, aircraft wing and tail attach fittings, wheel rim and bead seat areas, gears and shafts, forgings, and some castings.
