A transducer with a frequency greater than 10 MHz will most
likely be used
during an immersion test - ANSWER-Transducer
frequency usage
The reference holes in standard aluminum area amplitude
ultrasonic test blocks
contain flat bottom holes - ANSWER-Reference holes
in test blocks
The gradual loss of sonic energy as the ultrasonic vibrations
travel through the
material. - ANSWER-
Attenuation
A term used to describe numerous small indications on the
instrument display
resulting from test part structure, numerous small
discontinuities, or both. -
,ANSWER-
Hash
Ultrasonic waves transmitted into and received from the test
material in the form
of repetitive bursts of acoustic energy. - ANSWER-Pulse
echo testing
Metal blocks which contain one or more drilled holes to simulate
discontinuities.
- ANSWER-Reference
blocks
A testing method that is best for detecting a discontinuity in a
152 mm (6 in) thick aluminum plate lying parallel to the entry
surface at a depth of 76 mm (3 in). - ANSWER-Angle beam test
A method where the presence of a discontinuity will not
produce a specific
discontinuity indication on the instrument display. -
ANSWER-Through-
transmission testing
method
The depth of a discontinuity cannot be determined when
using the through-
transmission testing method. - ANSWER-Depth
determination
,When inspecting coarse-grained material, a sound wave is
most easily scattered by the grain structure by a frequency of
2.25 MHz. - ANSWER-
Scattering frequency
The thickest crystal is contained in a 25 MHz transducer.
- ANSWER-
Transducer
thickness
Indications may result from improper frequency, oil on the
surface, a surface discontinuity, or the acoustical velocity of
aluminum. - ANSWER-Surface wave test indications
The largest display indication results from a 2 mm (0.08 in)
diameter flatsurfaced discontinuity whose major face is
perpendicular to the direction of sound beam propagation. -
ANSWER-Display indication
Transducers constructed with a plastic wedge or standoff
between the transducer element and the test piece are
commonly used for angle beam contact testing. - ANSWER-
Angle beam contact testing
A transducer containing three or more individual
transducer elements. -
ANSWER-Mosaic
transducer
, Sound can be focused by means of special curved adapters
located in front of
the transducer element, referred to as acoustic lenses. -
ANSWER-Acoustic
lenses
A test method in which the parts to be inspected are placed in
a water bath or
some other liquid couplant. - ANSWER-
Immersion testing
A separate time base line imposed on the viewing display of
some ultrasonic
testing instruments that permits measurement of
distances. - ANSWER-
Time/distance
line
A term used to describe the ability of an ultrasonic testing
system to distinguish
between the entry surface response and the response of
discontinuities near
the entry surface. - ANSWER-
Sensitivity
The phenomenon whereby an ultrasonic wave changes
direction when the
