It can be seen from this relationship that beam spread can be
controlled by selecting a transducer/probe with a combination of
higher frequency or larger element diameter.
4.3 Straight Beam Testing
Straight beam testing is the introduction of the sound energy
normal to the test piece surface utilizing longitudinal or
compression waves. A longitudinal wave is one in which the
particle motion is in the same direction as the propagation of the
wave. Straight beam testing is used for most flaw detection and
thickness gauging.
4.4 Dual Element Testing
Dual element transducer/probes contain separate transmitting and
receiving elements as shown in Figure 4, usually mounted on
delay lines with a slight included angle. This design improves near
surface resolution by separating the initial pulse from the received
echoes and by providing a slight focus of the sound beam. Dual
transducer / probes are therefore, suitable for the thickness
gauging of pitting and corrosion. Although dual element angle
beam transducer/probes are made for special situations, almost all
dual element transducer/probes are used for thickness gauging of
corrosion.
