Automated Ultrasonic (UT)
Weld and Flaw Inspection
The automated ultrasonic (UT) system provide high speed accurate
measurements for weld / flaw detection. The instruments are
fully programmable / configurable to provide high resolution C-Scans
of weld seams for a large number of different structure geometries.
The instruments perform inspections quickly (about 0.5m/min
linear scanning velocity), with resolution, in this case, of 1.25
[transverse to weld] x 6 mm. The results are available in real-time,
and consist of color-coded amplitude "maps" corresponding
to the severity of the indications found. Location (depth) of
defects can be determined using time-of-flight data, which is
also recorded along with the amplitude data.
As shown on the accompanying figures, the ultrasonic data, which
is available as either 2-D or 3-D C-Scan images, shows both the
presence and location of a weld defect. The same defect is shown
on the corresponding x-ray image on the left.
