ECT For Bars

• Automatic bar feeding system
• Automatic marking and sorting of defective bars during testing
• Size range: 6 to 60 mm
• Inspection of Longitudinal / Circular Surface defects
• Detectability of ECT: 0.05mm depth flaw with length 5mm I Detectability of ECT: 0.05mm depth flaw with length 5mm
• Reliable and reproducible test results I Reliable and reproducible test results
• High production speed

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 byextrapolation 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
