  6. Acoustic and Electromagnetic Methods

The use of acoustic and electromagnetic methods in the development, validation and application of non-destructive testing methods constitutes the focus of the Acoustic and Electromagnetic Methods division.

We detect surface-level and hidden inconsistencies, defects and material changes before damage develops. Studies are conducted in the laboratory, in the production facility, or while components and machinery are in operation.

  • Fields of expertise

    • Ultrasonic and electromagnetic non-destructive testing
    • Simulation and modelling of testing methods
    • Design and development of optimised testing methods
    • Visualisation and reconstruction of testing data to enable improved error detection and evaluation
    • Validation of NDT methods, test reliability and testing instructions
    • Accredited testing laboratory in accordance with DIN EN ISO 17025

  • Main activities

    • Mechanised and imaging ultrasonic testing
      - using phased arrays in contact testing
