Which components can be tested with ultrasonic testing?

Ultrasonic testing can be used to inspect all components and materials that are transmissive to ultrasound, such as metals, plastics, and composites. The suitability depends on the acoustic impedance and sound hardness of the material. In cast and forged components, manufacturing-related inhomogeneities can be detected immediately after production. Weld seams can be tested from a wall thickness of 8 mm using conventional ultrasonic testing, and from 6 mm using phased array techniques. Zeros GmbH also has extensive experience in project-specific validations to reliably inspect components with wall thicknesses below 6 mm using phased array technology.
