Flux leakage inspection of black and bright ferro­magnetic metal bars and seamless tubes

FAQ

Flux leakage testing

What is magnetic flux leakage testing?

Magnetic flux leakage testing is a non-destructive method of detecting flaws on both the inside and outside of semi-finished ferromagnetic metal products.

Why is magnetic flux leakage testing important?

Magnetic flux leakage testing is important because it increases safety by identifying material defects before the materials are used.

How does magnetic flux leakage testing work?

Magnetic flux leakage testing uses a strong magnet to magnetize the conductive, ferromagnetic material being tested, such as steel. If there are defects, such as pits, corrosion, or material loss, the magnetic field “leaks” from the metal. The testing equipment uses the concentration of magnetic flux on the conductive material to identify flaws in the material.
