What code or standard are you examining to and how is the accept/reject criteria established matched with understanding where the sound is actually going is a good place to start. API RP 2X has a good methodology to the examination of structural connections so I would study that. If you are new to this a well built mock up to practice on is essential.
TKM-459CE combi applies 2 methods of hardness control: UCI and
Leeb. It provides high-accuracy tes
ting of metals and alloys as
well as items of different sizes and configurations, their
hardened layers and galvanic coatings. Device represents results
in HB, HRC, HV and others. Shock-, dust- and water-proof housing
with intuitive software make this gauge easy to use in all working
The conformability is obtained with a flexible membrane filled with water between the transducer and
the inspected component. The coupling between the membrane and the component requires a small quantity of water or couplant. The conformable wedge combines the acoustic performance of immersion technique with good coupling and low attenuation.
