    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

    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 material SNR.
