The Testex, Inc. developed Hawkeye 2000 System is based on the principles of Balanced Field Eddy Current. It is used to detect surface and sub-surface cracking in welds. With scanning speeds from a few inches/second to 1 foot/second, the Hawkeye 2000 is much faster than conventional NDT techniques such as Dye Penetrant and Magnetic Particle testing.
The Hawkeye 2000 System can be used for a multitude of welding inspections, such as, pressure vessel weld inspections, tube to header weld inspections, dissimilar metal weld inspections, etc. This system can virtually be used anywhere there is a cracking issue.

While the current TesTex Hawkeye Crack Detection Systems that are field deployed can detect a crack within 1/8" of the surface, new prototype sensors are detecting cracks within 3/8" of the surface. It also is a dry method, which needs minimal surface preparation.
