Stiffener inspection

Application example

Metallic welds inspection




13 MHz focused linear array probes for laser welds inspection

Probes

High resolution linear phased array probes for electronic scanning
Center frequency from 10 MHz to 15 MHz
Number of elements from 32 to 128 (typical)

Techniques

Pulse echo in Immersion for laser beam welded fuselage panel
Contact , pulse echo or tandem for butt welds

Benefits

Electroacoustic performances: very high sensitivity and short pulse
Inspection speed thanks to electronic scanning

Carbon or glass fiber stiffener inspection

temporal and frequency response of a 5MHz 64ch focused linear array

Pulse length (-20dB)
= 370 ns

Bandwidth (-6dB) = 90%

Probes

Linear phased array probes for linear scanning
Annular phased array probes for electronic focusing
Center frequency from 1 MHz up to 7.5 MHz

Techniques

Immersion or contact coupling
Pulse echo or transmission technique

Benefits

High sensitivity and large bandwidth more than 80% to manage material attenuation and filtering
High speed inspection thanks to eletronic scanning and focusing
Reliability in industrial using conditions
