Eddy current inspections can be used to verify proper assembly of critical components. Similar to a material structure inspection, this type of test looks for changes in an assembly under test verses a known good assembly. Any differences are flagged by the eddy current instrument, and a reject I/O indication is sent to the production line.
Eddy current feature tests can be performed in a few seconds making the inspection process easy to integrate directly into a production line.
Assembly Verification Test Examples:
- Confirm inclusion of shaft retaining keys or pins
- Verify metal keepers in rubber molded parts
- Validate proper number of burst discs inside an air bag inflator
- Check for proper orientation of piston rings
Other advantages of eddy current assembly verification systems include:
- Instantaneous responses
- Reliable, reproducible results
- Does not rely on system operator
- Easy integration into production lines for 100% part inspection rates
