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
