Sonotron NDT Announces the Mechanics Free Raster Scanning for the New ISONIC 3500 Series Instruments

Sonotron NDT76, Rehovot, Israel

Manual Raster Scanning remains to be the optimal solution for the numerous inspection tasks such as ultrasonic testing of relatively small composite parts, detection of impact damages under the flying surfaces of aircraft, corrosion mapping, and the like where the mechanic-free probe positioning is desired by most of users. The new airborne ultrasound based encoder from Sonotron NDT powered and communicating with the instrument through USB port monitors the probe position and swiveling angle for the conventional / PA probes manipulated over the flat or curved surfaces. The main module of the encoder carries the electronic box and the bar with airborne ultrasound receivers. Prior to the scanning it should be placed onto the part under test or at some proximity to it by means of either magnetic legs or vacuum cups. The encoder is connected to the instrument via USB cable and the umbilical extending the probe connection terminals. Another thin umbilical connects the probe used for the inspection to the corresponding extended terminal(s) and the airborne ultrasound emitter seating on the top of the probe to the electronic box. Single element airborne ultrasound emitter is sufficient for the XY-positioning of the probe; dual emitter is required for the XYγ-positioning where  is the probe swiveling angle

The probe coordinates on the material and swiveling angle are monitored continuously and transmitted to the inspection software providing capturing of the corresponding A-Scans (conventional modality) and A-Scan sets (PA modality) for every encoded position along the scanning trace. The inspection software packages created for the recently introduced ISONIC 3505 and ISONIC 3510 instruments allow:

  • Compression wave flaw detection and thickness (corrosion) mapping of the parts with flat and curved surfaces with use of single or twin element conventional probes and linear array / dual linear PA probes
  • Short Range Guided Wave (SRUT) inspection of annular rings, pipe walls, tank shells, and the like with use of mono-element SRUT probes and wedged PA probes
  • Weld inspection with use of PA probes
  • etc

The B-, C-, CB-Scan and 3D data presentation are provided

The same SW packages will be supported by the next-coming instruments of ISONIC 3500 series to be introduced in the near future. The VAUT technology is supported by the new inspection SW packages as well. The new airborne ultrasound based encoder is characterized by the high degree of the immunity to the industrial noise (acoustic and electromagnetic) and simplicity of the calibration and operation
