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.
