Producers of metal bars can find a whole range of different testing methods depending on their individual needs, starting from plain eddy current testing with encircling coils, on to testing inline at high production speeds with rotating systems of different sizes, and to ultra-sensitive flux leakage testing which is a reliable method to find miniscule surface defects.

Typical applications:

Hot rolled bar
Sheathed products

For normal quality needs, producers of black an bright bar can use an eddy current testing system to find defects and guarantee a semi-finished product of good quality.

For black and bright bar producers facing 100% top quality demands, NDT offers a new testing system that can find miniscule cracks reliably and reduce scrap and material expenses effectively: NOVAFLUX. This new system is based on the flux leakage method.

Typical applications:

Sensitive bar testing with NOVAFLUX
Black/bright bar testing
