Purpose
Automatic inspection of surface defects on cylindrical mandrels and small to medium diameter seamless pipes.
Key features
- Single module delivers transverse mandrel profile measurement and defect mapping
- Scanning frequency up to 8000 Hz
- Resolution: 0.25 mm × 0.1 mm over the mandrel surface
- Fully automatic alignment algorithm (sensor coordinate calibration) within a unified 3D reference frame
- Automatic full calibration device using reference standards
- High-speed dedicated data acquisition and processing software running on Linux
- Web-client user interface

Laser 2D scanner geometry control
Defect recognition is based on actual surface profile deviations (capturing surface profile and detecting recesses, protrusions, and other irregularities).

- Scanning frequency up to 8000 Hz
- Profile points per scan up to 1920
- Defect recognition from 0.2 mm (depth/length/width) with 0.05 mm resolution
- 100% surface coverage
