Test method
Acoustic resonance analysis (ART)
Hear cracks before they break.
What is it about?
The method in one sentence.
Acoustic resonance analysis (ART) is a non-destructive testing (NDT) method especially suited for economical 100 % inspection in mass production. It works on sintered, cast, forged and ceramic parts.
How does it work?
A broadband excitation – manual or automatic via impulse hammer – makes the part ring. SonicTC analyses the frequency spectrum, compares to a reference master and detects surface and volumetric defects.
Typical applications
- Crack detection on brake discs, sintered rings, cast parts
- Voids and microstructure defects in the part volume
- Material mix-ups in incoming goods inspection
- Sorting by sintering grades
- 100 % testing with cycle times below one second
