Description
Eddy current testing of long products and semi finished products with the ELOTEST \ PL650 test instrument, ELO \ LINE software and rotors. When testing long products for circumferential and localized defects, these are typically inspected by comprehensive ULAD-type differential test coils.
With the additional absolute coil, longitudinal defects such as slit seams in welded tubes can also be detected. Segment coils of type LDA are usually used for weld seam testing. These can be individually adapted for specific geometries.
The sensors are selected according to the testing requirements. Differential sensors with distance compensation are used for many tasks. The usual effective width is between 1 and 15 mm. Together with a suitable rotation speed of the coils, a very high throughput can be achieved in continuous operation.
