Immersion Flat with Radius (IFWR) Phased Array Probes

Immersion Flat with Radius (IFWR) Phased Array Probes

Overview

Evident 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 Evident 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 Evident 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

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

OmniScan X3 Series

Every flaw detector in the OmniScan™ X3 series is a complete phased array toolbox. Innovative TFM and advanced PA capabilities help you identify flaws with confidence while powerful software tools and simple workflows improve your productivity.

OmniScan SX

The single group, lightweight OmniScan SX flaw detector features an easy-to-read 8.4-inch (21.3 cm) touch screen and provides cost-effective solutions. The OmniScan SX comes in two models: the SX PA and SX UT. The SX PA is a 16:64PR unit, which, like the UT-only SX UT, is equipped with a conventional UT channel for P/E, P-C, or TOFD inspections.
