Acceptance Criteria

Minimum defect depth and length (FBH)

  • 0.7 mm FBH from 15—60 mm dia
  • 1.2 mm FBH above 60 dia

 
Minimum defect depth and length (SDH)

  • 0.5 mm x 10 mm {from 15—120 mm dia)
  • 0.3 mm SDH sensitivity can deduced by
    extrapolation depending on material SNR.

Phased Array Auto Ultrasonic Testing Salient Features

Phased Array Technology

Phased Array testing is a specialized type of ultrasonic testing that uses sophisticated multi- element array transducers and powerful instrumentation/software to steer ultrasonic beams through the test piece and map returning echoes.

No rotating movement, only electronic scanning is done:

  • Depth focalization for bar volume inspection (LW)
  • Electronic steering for bar surface inspection (SW)

Quality Highlights:

Capacity — 15 to 120 mm dia. Full bar volume inspection
