Learn about a few different tools you can use to tap your parts. The tapping makes an audible sound that can help you detect any defects.
- [Instructor] Tap testing, sometimes referred to…as audio sonic or coin tap.…This technique makes use of frequencies…in the audible range.…It's a surprisingly accurate method…in the hands of an experienced person.…Tap testing is perhaps the most common technique…used for the determination of damage, delamination,…and disbonding.…This method is accomplished by tapping the inspection area…with a solid round disk or a lightweight hammer-like device…and listening to the response of the structure…to the hammer.…
A clear, sharp ringing sound is indicative…of a well-bonded, solid structure,…while a dull or thud-like sound indicates…an area that has a discrepancy.…Automated tap testing is very similar to manual tap testing…except that a solenoid is used instead of a hammer.…The solenoid produces multiple impacts in a single area.…The tip of the impactor has a transducer…that records the force versus time signal of the impactor.…
The magnitude of the force depends on the impactor,…the impact energy, and the mechanical properties…
