  • Page 3: Probe Description

    1. Probe Description The medium Sharck™ probe used in this guide contains two rows of 11 independent fingers. This array probe (SHARCK-W053-R-N05S) offers a coverage or active area of 53 mm (2.1 in). Other sizes of Sharck array probes are also available.
  • Page 4: Teca™ Technology

    As illustrated below, this coil orientation helps eddy currents to dive underneath cracks, offering valuable information about their depth. Each finger of the Sharck probes contain three coils: two tangential operating in transmit/receive mode and a third whose axis is perpendicular to the surface under test. The tangential coils are used to measure the depth of cracks, while the third coil is used to position cracks, measure their length, and to detect transverse cracks.
  • Page 5 The main characteristics of TECA signals are: Almost flat liftoff signal • Crack-like indications approximately 90° relative to the liftoff signal • All crack-like indications feature the same phase shift • Signal amplitude linked to the defect depth • Figure 4 Liftoff and phase shift Obviously, the vertical amplitude of a given indication is impacted by lift off.

  • Page 15 Figure 22 Data definition: configuring filters Note Sharck probe setups are tailored for carbon steel. That is why you cannot change the frequencies and injection voltages of these setups. Moreover, as most channel groups are necessary for analysis, you can only disable the transverse group.

    5. Nulling the Sharck Probe 1. Position the Sharck probe on the plastic portion of Eddyfi’s normalization plate (REFPL-CAL- SHARCK-AAL-LG). Note The normalization plate should be on a steady, flat surface and shall be at least 10 cm (4 in) from any ferritic surface.
  • Page 19: Calibrating The Sharck Probe

    7. In the Sharck Assisted Calibration dialog box, tap Aluminum. When the necessary data is acquired, a green check mark appears next to Aluminum. 8. Position the Sharck probe on the carbon steel component to be tested, near the weld (but not over the weld) 9.
  • Page 20 Note If non-magnetic paint or coating is present, there is no need to remove it (unless it is thicker than 3 mm (0.118 in). The Sharck calibration process takes that lift-off into account and manages accordingly. 11. In the Sharck Assisted Calibration dialog box, tap Calibrate ( When the necessary data is acquired, a green check mark appears next to Calibrate.

    6. Placing appropriate pressure on the probe, move it longitudinally along the weld. Note The maximum speed is 200 mm/s (8 in/s) for the small (-W028) and medium (-W053) Sharck probes. 7. When scanning is done, press the Start/Stop acquisition button ( ) on Reddy’s keypad.
  • Page 22 Data is positioned according to the origin (0, 0) illustrated below. This is the top view of • the probe (transparency). Along the scanning axis, the origin is 38.75 mm (1.53 in) from the front of the probe’s casing (the front being the edge of the casing closest to the scan direction).

  • Page 26 When flaw-like indications are detected, you must isolate them with the cursor to obtain the sizing information (depth, length, liftoff, and position). Place your cursor over an indication and maximize the signal in the impedance plane view of the Depth C-scan you are using. In the Length C-scan, resize your cursor horizontally so that it contains the entire indication (the width of the cursor should be equal to the measured length plus 15 mm (0.59 in)).

    9c. Analyzing Data with Reddy Before analyzing data, if you want to include screen captures in your report, make sure that the following option is selected in Project (back stage view). If you do not, reports only include summaries of your findings. Figure 36 Take screen captures with defect report entry option 1.
  • Page 28 Figure 38 Entering a detected defect Notes The current sizing method appears at the bottom of impedance planes. Tap (2) to switch • methods in each view. To obtain appropriate measurements use the Average Peak Vertical (Vapv) method to measure depth and the Maximum Peak Vertical (Vmpv) method to measure length.
  • Page 29 Figure 40 Report tab Notes A crack-like indication is typically set at a 90°phase in the Short and Long C-scans, and 45° • phase in the Raw C-scan. Signals with a phase angle greater than 90° are generally characterized as transverse defects, while signals with a phase angle less than 90° are characterized as geometrical effects from features on the part under test.
