Overview

Acoustic Emission is Non-Destructive Testing (AE is NDT)

Acoustic Technology Group, Inc. (ATG) was founded in 1991 and continues today as a leading distributor of Acoustic Emission (AE) products. We represent OEM firms specializing in design, manufacture, and application development in the Non-Destructive Testing (NDT) technology of Acoustic Emission (AE).

ATG can speak with you about all applications of AE, from asset protection via advanced technology to specific details of structural health monitoring, laboratory experimentation, small-scale sample testing, partial discharge, rotating equipment monitoring, and leak detection.

We do not compete with our clients by providing AE inspection services but will refer you to some of the best, most experienced, and most reliable service companies in the USA.

Laser Acoustics

Laser Acoustics: Xarion

XARION offers proprietary, laser-based sensor technology for contact-free ultrasonic & Acoustic Emission testing. The inspection method enables an easy integration with existing systems, robot arms and software. 

Spot Wels Inspection

  • High-speed inspection on robot
  • No coupling liquid necessary
  • Reliable distinction between OK and NOK welds

Semiconductor Inspection 

  • Ultra high-speed inspection
  • Detection of delaminations and defects
  • Suitable for high-volume production lines

Ultrasound Testing of Composite Materials

  • Water-free ultrasonic testing of CFRP or adhesive layers
  • Detection of internal defects and delamination
  • Single-sided or through-transmission configuration

Laser Process Monitoring

Laser processes emit light – and ultrasound! The airborne ultrasound emission can be harnessed to monitor the quality of industrial laser material processes, e.g. laser welding, structuring or cutting as well as additive manufacturing such as powder bed fusion and direct energy deposition in real-time.

Crack Detection

The ultrasonic frequencies exceed the audible human hearing range 100-fold. In the ultrasound regime (free from background noise), crack signals of brittle materials, such as ceramics or high-strength alloys, can easily be picked up by the optical microphone to trigger a warning signal to the production line.

AI-based Machine Diagnostics

Due to the Optical Microphone’s immense frequency bandwidth, every recording contains a vast amount of data available for feature extraction. We utilize classification and regression, SVM algorithms, k-means clustering and other methods to achieve unprecedented correlation between acoustic process signal and final product quality.
