Thiết bị dò tìm khuyết tật bằng siêu âm mảng pha (PAUT) – GEKKO

 

Benefits

  • Increased accuracy with high-resolution imaging
  • Advanced defect analysis with Total Focusing Method
  • Robust field unit with high battery autonomy
  • Easy setup with embedded scan plans
  • Evolutive software following inspectors feedback

Applications

  • Multi-group weld inspection procedures fully covered
  • HTHA and hydrogen damages inspection with TFM
  • Thick welds and CRA/stainless steel weld inspection enhanced with 128-element aperture
  • Corrosion mapping of large areas (up to 5 × 5 m [16.4 × 16.4 ft] / 1 mm [0.04 in] step)
  • Complex geometry dedicated solution for nozzle and fillet welds (Y and T joints)

Streamlined Workflow

Powered by Capture, the new generation Gekko has been designed to ease the setup process and save time for the inspectors operating in tough environments. The newly added onboard scan plan and analysis features join the popular 3-click wizards for evaluation of material velocities, amplitude balancing of the transducer, flat and curved wedge calibration, as well as the automated TCG. Enriched to offer an all-in-one inspection solution—from application design to inspection and reporting—Capture offers the latest phased array technologies in a couple of clicks.
