The use of acoustic and electromagnetic methods in the development, validation and application of non-destructive testing methods (NDT) as well as the human factor analysis in NDT 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.
