Immersion Flat with Radius (IFWR) Phased Array Probes


Immersion Flat with Radius (IFWR) Phased Array Probes

Overview

Olympus manufactures custom immersion flat with radius (IFWR) phased array probes to increase coverage, improve detectability, and simplify data analysis. Mistras Group Inc. has increased productivity by using a single custom Olympus 3.5MHz 64 element IFWR probe; replacing two probes in their composite inspection setup. Mistras Group Inc. provided the following details and graphics outlining their success.

Old Technique

Mistras previously used 1 linear 64 element, 1 concave 32 element probe, and the OmniScan MX to inspect 8 zones across a composite part. The inspection with two probes took approximately 2.5 hours.

The C-scan data recored from multiple probes and passes becomes more difficult to record and analyze. Each scan must be properly identified to ensure acurrate analysis.

New Technique

Using the Olympus custom IFWR probe, inspection of all 8 zones can be completed with one probe in two passes; reducinig inspection time by approximately 50%.

Reducing quantity of probes while increasing coverage has proven to simplify recording and analyzing data. Each part now has only two C-scan’s to analyze.

Conclusion

Olympus has worked with Mistras Group Inc. to provide a custom probe which has proven to reduce inspection time, improve detectability, and simplify data analysis. Olympus has the capability to manufacture IFWR probes to customer specifications and specific part requirements.

Produits utilisés pour cette application
Chaque appareil de la série OmniScan™ X3 constitue en lui-même un coffre à outils complet pour l’inspection multiélément. Des capacités TFM innovantes et PA avancées vous aident à identifier les défauts en toute confiance, tandis que des outils logiciels puissants et des flux de travail simples améliorent votre productivité.
De conception compacte et légère, l’OmniScan SX effectue des inspections économiques à un seul groupe en plus d’offrir une nouvelle interface utilisateur simplifiée sur écran de 8,4 po. L’appareil est offert en deux modèles distincts : SX PA et SX UT. Le modèle SX PA est une unité multiélément 16:64PR et, tout comme le modèle SX UT, il est équipé d’un canal UT conventionnel pour les inspections TOFD, par réflexion ou par émission-réception séparées.
L’OmniScan MX2 offre un module à ultrasons multiéléments (PA2) muni d’un canal UT, un module à ultrasons conventionnels à deux canaux (UT2) qui peut être utilisé en mode TOFD, ainsi que des logiciels qui permettent d’accroître l’efficacité de cette populaire plateforme d’inspection.
