HAWK-EYE 2000 WELD SCANNING SYSTEM
FOR CRACK DETECTION
A REVOLUTIONARY TECHNIQUE HAS BEEN DEVELOPED FOR
THE DETECTION OF CRACKS IN WELDS & OTHER MATERIALS. 
 

TesTex introduces one of the most innovative systems for the detection and sizing of both surface and sub-surface toe-cracks in welds and base metals. Although the current system and geometric configuration is most suited for the inspection of lap welds in storage tank plates, the system is adaptable for the detection of toe-cracks in other welds such as butt, toe, fillet, etc.

This system is based on the eddy current principles of electromagnetic techniques and replaces the old and laborious techniques such as vacuum box, dye penetrant or magnetic particle inspection. The technique is quantitive and gives the depth and length of cracks. Unlike UT, the system does not demand a clean surface and is forgiving to scale, corrosion products, etc. With scanning speeds up to 1 ft./second, the system is fast, accurate and efficient for the evaluation of toe-cracks in welds.


Flaw signal from a sub-surface 6mm EDM notch incorporated into a lap weld. Plate thickness is 0.0375 in. Scanning speed is approximately 1ft/sec.

Advantages:
* Paints/coatings and corrosive products have no impact on flaw signal
* Requires only minimum surface preparation
* Unlike UT, requires no couplant - dry method
* Testing speeds from a few inches/sec to 1 ft./sec
* Elimination of liftoff/noise signals using special algorithms

Features:
* Realtime display of flaws
* Signals are digitized and stored for future trending purposes
* DSP based electronics platform
* Scanners with various profiles to fit the weld outlines of lap, butt, tee, fillet, etc.
* Enhanced S/N ratio using special noise reduction techniques

Versatility:
* Can be used for different lapweld sizes for 6mm, 9mm and 12mm thick plates
* A single envelope system for 1,2 or 3 sensors
* Adjustments for sensor orientation
* Separates weld data from heat affected zone data


System Specifications:
* Works with Falcon Mark II Electronics
* Size 4" (10cm) x 2" (5cm) x 3" (7.6cm)
* Wt. 1 lb (<0.5kg)
* Channels: Up to 4
* Power: 12VDC or 110/220 VAC
