#### Description

Weld inspections of fabricated plate and pipe assemblies made with shear wave angle beam transducers are a common and important application of ultrasonic NDE. It is now possible to develop complete models of such angle beam inspections (see, for example, the measurement model of Thompson and Gray [1]) for many practical configurations. One important element in these models is the calculation of the fields generated by the angle beam transducer, i.e. the transducer beam model. To date, three different beam models have been derived and studied. They are the Surface Integral model [2], the Boundary Diffraction Wave (BDW) Paraxial model [2], and the Edge Element model. Each has certain advantages and disadvantages associated with it, as will be seen in later sections of this paper.

Modeling the Ultrasonic Radiation of Shear Wave Angle Beam Transducers

Weld inspections of fabricated plate and pipe assemblies made with shear wave angle beam transducers are a common and important application of ultrasonic NDE.
