Sensitivity test strips are mainly used to test system sensitivity and verify the comprehensive performance of magnetic particle testing equipment, magnetic powder and magnetic suspension.

The remanence method is mainly used for the workpiece to be inspected with a coercive force of 1 kA/m or more and a sufficient residual magnetic field (remaining magnetization of 0.8 T or more).

The unveiling ceremony of the joint R&D center of Advanced Non-destructive Testing Technology and Equipment established by HATATEST detection and Beijing University of Aeronautics and Astronautics was successfully held in HATATEST on February 8, 2018

Magnetic particle inspection device by weight and mobility: fixed, mobile, portable; according to the combination of equipment: integrated and discrete

with reference to foreign advanced technology, the domestic testing level has been improved, The level of NDT technology for domestic aerospace composite materials has been greatly improved.

The method of crossing the yoke must use a moving magnetized workpiece to apply a magnetic suspension while moving the yoke.
