Cracks or defects in a material can disrupt the magnetic domain structure and cause changes in the Barkhausen noise signal. By analyzing the Barkhausen noise signal, it can be possible to detect microstructure changes next to crack and this can be used to localize cracks.
By verifying the crack with other methods one can find how the cracks affect the barkhausen noise signal and use that information for NDT crack detection.
We provide Barkhausen noise inspection systems for a wide range of steel components in following automation levels:
Inline/Robot Systems
RoboScan is an automated grinding burn and heat treatment defect detection system that can be integrated into production line.
Automated systems
Automated systems for quality inspection are tailored for offline use. Easy to use software makes inspections intuitive and systems can adapt to various component types.
Semi-automated systems
Semi-automated and manual Barkhausen noise analysis systems are suitable for low volume measurements. The most simple Barkhausen noise measurements can be performed handheld with only a sensor and analyzer.
Manual systems
Customized manual Barkhausen noise stands are grinding burn and heat treatment defect detection systems for low-volume applications.
