NDT Weld Crack Detection with BFET

The Hawkeye 2000 and its variants use the principles of Balance Field Electromagnetic Technique (BFET) to detect surface and sub-surface cracking in welds and base metal. With maximum scanning speeds of one foot per second, the Hawkeye 2000 is much faster than conventional NDT techniques such as dye penetration and magnetic particle testing. The Hawkeye 2000 can virtually be used anywhere that cracking is an issue, including the scanning of both ferrous and nonferrous metals. It can be used on pressure vessels, general vessels, windmill towers, storage tank floors and shells, and bridges.

The Hawkeye 2000 offers real-time data processing, and data can be displayed in horizontal, vertical, and impedance planes. Noise and liftoff can be rotated away from the flaw signal. It offers up to eight (8) channels and a frequency range of 5Hz – 30KHz.

Crack Detection Waveform
Waveform represents a crack detected in a coil weld.

The Hawkeye 2000 has many weld applications, including tube-to-header weld and dissimilar metal weld inspections. It also works on a variety of different types of welds, including butt-welds, lap-welds, and T-welds. For butt welds, no couplant is needed, the Hawkeye offers four inches (101mm) of coverage per pass and inspects both sides of the weld with one pass.

For vessel inspection, the Hawkeye 2000 requires minimal surface preparation and detects cracks, undercuts, porosity, slag, etc.

On surfaces, the Hawkeye 2000 requires minimal preparation and detects surface and sub-surface cracking without coatings.

The Hawkeye detects cracks to a depth of 0.125 or one-eighth-inch (3mm) from the surface in carbon steel, and it covers a swath of up to eight (8) inches (203mm) on a single pass.
