There are two types
in Angle Beam Transducer: longitudinal wave transducer
and shear wave transducer. Of these, shear wave transducer
is used in more cases.
|
|
|
Shear wave transducer is the main products
of TKS Corp and longitudinal wave transducer
is being in production upon purchase order.
Standard Series are for normal testing without
heavy attenuation. The irregularities in their
surface of the cases prevent slipperiness and
they are designed with the power set downward
of the sensor to facilitate the contact with
testing subjects.

Main testing subjects
are welding part of container-kind( e.g. boiler's vessel)
as well as a normal welding part, the crack of axis
of rotation, or parts with much stress pressured on
in machinery-kind.
Lemo Connector is equipped to bring upward the ratio
of S/N in linking with ultrasonic instrument.

Formation, material, and thickness
of testing subjects are taken into consideration
in selecting oscillator's size and frequency. In
testing welding parts, limited access distance,
weld bevel angle, and anticipation of defect orientation
are factors to be considered in selecting refraction
angle. |
