Advantages of immersion Testing
Ability to use higher F
Ease in angulating the sound beam
Ease in scanning the test speciman
better resolution due to reduced dead zone and near field.
No special couplant is necessary
Uniform coupling, improved repeatability
water path
In immersion testing, the distance between the transducer and the test material
Water path thickness limitations
waterpath must be greater than 1/4 the material thickness
Focused Transducers- purpose
Can direct the beams more perpendicularto the surface of the test piece
Focused Transducers- Types
Lenses are convexed and concaved.
Focused Transducers-Advantages
Focused transducers counteract the long near field length of high frequency transducers.
