Description
The NORDISCAN-PL series Scanners are intended for fully automated off-line ultrasonic examination of body and edges of plates, coils, slabs, and ingots. NORDISCAN-PL systems are designed to perform fully automatic high performance inspections of flats outside of the production line on a charging table. The system utilizes our advanced software and displays the defect map in real-time mode, and simultaneously saves the results on a local or external drive for further evaluation, re-evaluation and analysis.
The NORDISCAN-PL series achieves multiple inspection tasks:
Detection of internal imperfections in rolled plates, ingots, and slabs such as: laminations, non-metallic inclusions, porosity, shell, sponge, etc.;
Detection of surface and sub-surface defects;
Detection of zones of mechanical properties uniformity (Hard Sports);
Precise wall thickness measurement;
Plate Geometry Monitoring.
Main Ultrasonic Testing Parameters
