Facilities

CNDE has a variety of ultrasonic transducers of various types (immersion, contact, phased array) and several dedicated ultrasonic inspection systems.  CNDE also has developed inspection simulation software which allows one to view, for a given inspection setup, the expected pressure profile of the incident sound field within the component under inspection.  This capability, as illustrated below, can be very helpful when designing inspections.

The color inset shows how the incident sonic pressure field inside the metal is expected to vary with depth within an axial/radial plane of the metal component.  Here a focused sound beam is being used, with the focal plane located about mid way through the component thickness.

Photographs of three of the available UT scanning systems at CNDE are shown below.  The larger UT systems bear the whimsical names “Moe”, “Curly”, “Larry” and “Shemp”.

Shemp, It has two computer controlled masts for manipulating transducers, and can accommodate either a turntable or a billet rotator.
