Depending on the customers' needs, the Olympus rotating large billet inspection system can combine both eddy current array (ECA) and phased array UT (PA) technologies permitting a 100 % inspection of the billet volume and surface.
Ultrasonic phased array (PA) and eddy current array (ECA) rotating billet inspection system
Designed for:
- Round Billets
- Aluminum, carbon steel, and stainless steel
- Diameter range: 50 mm (2 in.) to 850 mm (33 in.)―depending on the materiel type
- References:
- Flat-bottom hole (FBH)
- Side-drilled hole (SDH)
- Surface notch
System Key Features
The main characteristics of the Olympus rotating billet inspection system are:
High Productivity
- A large mechanical scan overlap covering up to 120 mm/revolution causing a relatively slow billet rotational speed
- Versatile system quickly reconfigurable to different inspection configurations:
- Fast mechanical changeover time
- Quick access to predefined inspection setups
- Software Wizard tool used to create new inspection setups
- Multiple parallel firing to inspect simultaneously at different positions on the billet
Quality
- Full body inspections of the billets by combining:
- Ultrasonic phased array (PA), longitudinal wave (LW), and shear wave (SW) for volumetric inspections
- Eddy current array (ECA) technology for surface inspections
- Unique cluster/water wedge (WW) concept allowing:
- Many degrees of freedom to follow pipe movement
- Perfect coupling, even with important straightness variations
- Mechanical design allowing small untested billet ends.
- Automatic calibration per channel providing the greatest documented repeatability in the industry with detailed data reporting.
- High sensitivity on small reference defects with SNR greater than 12 dB.
- Back-wall echo removal UT function for detecting defects below the surface (reduction of the dead zone)
User Friendly
- Easy interpretation of the inspection results using real time strip-chart displays
- Easy and fast mechanical reconfiguration between two billet sizes
- Detailed alarms and data reporting
- Supervisor software used to:
- Merge and archive inspection data in one common database
- Centralize inspection results and real-time displays on a single work station
- DCOM exchange protocol for easy interface with customer level 2 production-line systems
- Easy maintenance
- Multilingual acquisition software
