Permanent magnet yoke
Equipment comprising two magnetic north and south poles which, spaced apart and applied to the test surface, induce a true DC magnetic field in the area of the part located between the two poles.
Circular magnetization
A magnetization technique in which current is passed through the part to be inspected from one end to the other, generating a circular magnetic field and enabling longitudinal discontinuities to be detected. This type of magnetization can also be obtained with a threaded conductor.
Longitudinal magnetization
Magnetization whose magnetic field lines are essentially parallel to the longitudinal axis of the part to be inspected, enabling transverse discontinuities to be detected.
Multidirectional magnetization...

Events
COFREND Days (French Confederation for Non-Destructive Testing) take place every three years in a French city chosen by COFREND. Those celebrating COFREND's 50th anniversary took place from May 30 to 1 er June 2017 at the Palais des Congrès in Strasbourg. The COFREND 2020 Days were cancelled due to the health and economic context, which had a strong impact on event activities in France....
