Ultrasonic Transducer/Probes Angle Beam Transducer for Nondestructive testing
Model No: 2.5P9X9A70
Connector: Q6
Angle Beam Transducers are single element transducers used with a wedge to introduce longitudinal or shear wave sound into a part at a selected angle. Angle beam transducers allow inspections in areas of a part that cannot be
accessed by the ultrasonic path of a normal incidence contact transducer.A common use for angle beam transducersis in weld inspection,where a weld crown blocks access to the weld zone of interest for a standard contact transducerand where typical flaw alignment produces stronger reflections from an angled beam.
Transducers for the Contact Inspection Method
Angle Beam Transducer
Element mounted on integral or replaceable wedge
Uses refraction to transmit shear or longitudinal wave at a predetermined angle
Most standard transducers generate shear waves by mode conversion
Preferred for parts with inclinedflaws, such as welds
Available in both single and dual element types
Requires couplant layer, typically a gel, oil, or paste
Sometimes used in mechanized or automated testing
Application:
a. Common welding inspection.
b. Pipe casting, pressure wessels, storage tank.
c. Turbine blades and pressure vessels.
d. Wheel axle, forged piece and casting.
e. Railway wheels and railway rail.
