Barkhausen Noise Analysis (BNA) NDT

The foremost reason to use the BNA method is that this can be applied simply during the production process, without having to release the product and therefore without interruptions.

BNA is often applied as a method of control with the production of gears and
bearings and in several branches, including the automotive and aerospace industry. BNA can be applied to grinding, turning and milling operations of all ferromagnetic materials.
Also recognizing heat treatment defects as decarbirisation, soft spots and errors in induction processes.

•	The early detection of defects in your product before it is rejected
•	It is a non-destructive testing methode
•	Early detection of changes in microstructure and hardness
•	By using Viewscan software its easy to visualize the process.
