Ultrasonic
Inspection
|
Ultrasonic examination of structural
welds.
|
Ultrasonic techniques are particularly adaptable for determining
the structural integrity of engineering materials.
Their principal applications consist of :
1. Discontinuity detection and sizing.
2. Thickness measurement.
|
|
The desirable features of UT include:
1. High sensitivity permitting detection of minute
discontinuities.
2. Good penetrating power, allowing examination of extremely thick
sections.
3. Accuracy in the measurement of discontinuity position and
estimation of discontinuity size.
4. Need for access to only one surface of test object.
|
|
Test conditions that may limit the application of UT typically
relate to one of the following factors:
|
|
1. Unfavourable test object geometry (size, contour, surface
roughness, complexity and defect orientation.
2. Undesirable internal structure (grain size, structure porosity,
inclusion content or fine dispersed precipitates.
Our ultrasonic inspection service includes the inspection of:
* Weldments
* Castings
* Forgings and rolled produces
* Thickness surveys (up to 600°C)

Eddy Current
Testing
Locates and measures the severity of surface and near surface
discontinuities in both magnetic and non-magnetic conductive
materials. In addition it can sort both classes of metallic
materials according to such properties as conductivity , chemical
composition and heat treatment.

Magnetic Flux
Leakage
Due to its ease of use magnetic flux leakage (MFL) is ideal for
testing ferro-magnetic pipelines and flat plate. It is used as a
rapid screening tool to test large areas for corrosion loss and
thinning. The MFL test locates the areas of thinning thus
eliminating the hit and miss of single spot and grid thickness
surveys. Once the thin areas have been located ultrasonic thickness
measuring confirms the remaining steel thickness at the indicated
locations.
The MFL test covers nearly 100% of straight test item to with in
150mm of flanges and welds. It eliminates most of the uncertainty
of single spot and grid thickness surveys. Each unit scans approx
150mm wide strip of the pipe or plate with travel speeds of up to
0.5m /sec. Each unit can be calibration so that smaller pits or
groves are disregarded and only those pits that are of concern are
indicated. I.e. if more that 50% loss is unacceptable the units can
be calibrated to 50% of wall thickness and any lesser loss is
ignored.
MFL works by magnetising the steel to saturation level. Which
produces a uniform magnetic field between the poles of the magnets
in the un-corroded plate. As the magnet bridge passes over a
corrosion pit, the constricted path causes part of the magnetic
field to break free from the plate. This leakage field is detected
by the hall effect sensors and is passed to the recording &
analysis circuits for display to the operator. The display unit
divides the width of each unit in to 6, thus the defect is located
to with in 25mm. Once the defect is marked ultrasonic thickness
gauging is used to determine the remaining wall thickness. Units
such as the Krautkramer DMS 2 with their minimum capture
capabilities are perfect for locating the actual defect.

Ultrasonic Thickness
Measurement
The DMS 2 is a revolutionary A-Scan Digital Thickness Gauge. All
pertinent inspection data is displayed to the user on a large high
resolution 1/4 VGA display designed to use direct sunlight to
enhance the contrast.
As well as having all the standard features of digital thickness
meter the DMS 2 extends the test possibilities with the
following.
|
Display of DMS 2: with the actual
thickness at the top and the A-Scan display of the signal
below.
|
A-Scan: Included with the digital readout of the thickness is
the A-Scan representation of the signal in the material, as
pictured to the right. This is beneficial as the operator can
distinguish between paint thickness, the actual thickness of the
part and that of incorrect readings being returned by defects or
reflected sound.
Features using the A-Scan display:
MINIMUM CAPTURE:
Measuring at 32 reading per second, it allows for fast
continuos scanning by recording the minimum thickness
automatically. Which allows the operator to concentrate on the area
to be scanned. Thus making minimum capture ideal for the
interpretation of the areas discovered by Magnetic Flux Leakage
Tests. By scanning 100% of the area marked by MFL the DMS 2 finds
the lowest point and records the result for the operator. When used
in conduction with the alarm (set to the min. thickness allowed)
the actual spot or area is readily marked even with out looking at
the DMS 2
FREEZE locks the A-Scan
display for evaluation and verification of the echoes at any time
during testing even while performing MIN CAP. This helps the
operator understand the results obtained with out the probe in
contact with the job, ideal for high temperature work.
GAIN (The intensity of the
signal) is readily adjustable in 1 dB steps via a direct access
key. Where normal thickness meters have only one setting. The DMS 2
can vary the gain so that results can be achieved where normal
thickness meters fail. I.e. on unparallel sections & uneven
surfaces (pits)
Store/Recall: Up to 20
parameter sets are recordable so that for repeat jobs the DMS 2
set-up and parameters are recorded for easy reloading to save
time.
|
B-Scan (Sample shown): To
quickly identify and picture, a reas of extensive corrosion or
delamination. The DMS 2, B-Scan provides a graphical thickness
cross-sectional view of the equipment being tested. B-Scans are
very helpful in quickly identifying laminated or heavily thinned
areas. Pit size and contour can be easily mapped giving a
representative view of the extent of corrosion pit damage.

The DMS 2 Data Recorder is designed to be the most comprehensive
data recording tool available. Storing 150,000 readings with A-Scan
or B-Scan graph for easy download and report generation. |
