PhaseX128 – Ultrasonic phased array flaw detector

Ultrasonic flaw detectors

The PhaseX128 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.

• 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
• 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
