Angle Beam Testing

Ultrasonic testing technique using transducers mounted on wedges at specific angles (typically 45° or 60°) to generate shear waves that travel at angles through the material. Angle beams are essential for detecting defects perpendicular to surfaces and inspecting welds from one side. The angle is calculated using Snell's law to achieve the desired refracted angle. Proper angle selection and beam geometry verification are critical to inspection effectiveness.
