Ultrasonic Flaw Detectors

Ultrasonic flaw detectors are one of the most common non-destructive testing technologies. The process is based on the propagation of ultrasonic waves through the material being tested. The shape and frequency of the reflected pulses can then be used to detect internal flaws or characterize the structure of the sample. The device generates waves with very short frequencies (0.1 - 15 MHz) and transmits them into the material being tested through a transducer probe and a thin film of couplant. Most of the materials that are tested are steel or similar alloys; however, ultrasonic flaw detectors can also be used on concrete, wood, ceramics, and other solid composite materials, though lower resolution results will be obtained.

This form of NDT is most commonly used to detect hidden cracks, voids, porosity, and other internal weaknesses in manufactured materials. Ultrasonic flaw detectors are used in most manufacturing industries including metallurgy, aerospace, and the automotive sectors.

For many years, Krautkramer was the leading manufacturer of ultrasonic flaw detectors. However, in 2004, General Electric Inspection Technologies (GEIT) acquired Krautkramer. Much of their existing catalog continued on with General Electric and their devices have since become more advanced.

Before its sale to GE, the name 'Krautkramer' had become the industry standard term to describe any type of non-destructive ultrasonic flaw detector. More than a decade later, Krautkramer remains a legacy name that most industry professionals and NDT engineers use out of habit and familiarity.

Whichever term you're most comfortable using to describe ultrasonic flaw detectors, the staff at Berg Engineering is ready to help you select the best ultrasonic flaw detection device for your application. We stock many transducers and other accessories that can be used on older Krautkramer devices. We also carry accessories and parts for newer devices from GEIT like the USM Go+ and PhasorXS. Also, if you're familiar with Krautkramer offerings of the past but now need to upgrade your equipment, give us a call and we'll help you get the model that has the features you want with the functionality that you need. You can reach us at 847-577-3980 or by emailing info@bergeng.com. Our knowledgeable sales engineers are here to assist you.
