I can't help you with free NDT material but I can offer some very inexpensive NDT Programmed Instruction and Classroom Training texts. We published the revised NASA/General Dynamics series and the cost is only $15-$18 per book.
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.
The Exertus Dual 120 Projector has the ability to accept Iridium 192
sources or Selenium 75 source
s. This projector incorporates design
safety features that make it flexible, compact and lightweight.
The Projector is lighter than most of its competitors. It
incorporates an improved source channel, based on a new helicoidal
design, which makes maintenance easier. The helicoidal design also
allows smoother movement of the source assembly inside the device,
making it easier for the operator and improving safety. The
Projector also has a unique safety feature not found in competitive
The source assembly locking mechanism is triggered by the source
holder capsule at the front of the source assembly, thereby always
assuring the operator that the source has returned to the
safe position. The Exertus Dual 120 is ISO3999:2004 compliant.
