TOFD Inspection – RF B-Scan &
D-Scan Imaging
-
Both time-based (real time clock) and true-to-location (built-in incremental encoder interface and mechanics free airborne ultrasound encoder) mode of data recording are supported
-
Averaging A-Scans whilst recording as per operator's selection
-
Complete sequence of RF A-Scans is recorded along with TOFD map
-
Off-line evaluation of TOFD Map is featured with:
-
Improvement of near to surface resolution through removal of lateral wave and/or back echo record
-
Linearization and straightening
-
Increasing contrast of TOFD images through varying Gain setting and/or rectification
-
Defects pattern analysis and sizing
-
Zoom of TOFD Map and A-Scans
Typical Application: Weld inspection
