TQ-60-X – Ultrasonic phased array flaw detector
Ultrasonic flaw detectors
The TQ-60-X is a high-performance ultrasonic flaw detector designed for simultaneous operation with two 64-channel phased array probes and a variety of scanners, including roller scanners and combined PA+TOFD scanners. With an S-scan refresh rate of 100 Hz, it enables high-speed weld inspection from both sides at up to 6–9 meters per minute.
The device also supports up to two TOFD channels, meeting global inspection standards. A classic flaw detection mode is included. An advanced software package provides automated data collection, image processing, and 3D visualization for detailed evaluation.
Application
- Weld inspection using phased array and TOFD techniques
- Automated scanning with 2D scanners
- Defect detection in metal structures
- High-speed, high-resolution inspection of complex geometries
- Post-scan 3D analysis and reporting
Operational advantages
- Supports full weld geometry definition, including wall thickness differences, cap bead dimensions, and heat-affected zone width (image 1)
- Universal, clearly structured probe positioning on the scanner ensures precise data alignment into a unified scan (image 2)
- Up to 4 inspection groups can be configured for each phased array probe
- High-resolution imaging with multiple scanning types:
– Classic S-scan
– Fixed-angle L-scan
– Combined LS-scan (compound S-scan with beam swing and aperture movement
