DEFECT ANALYSIS WITH
Non-destructively detect cracks, inclusions or pores without the need of coupling agents
How does a defect analysis with air-coupled ultrasonics work?
The sound is reflected or scattered by defects or other inhomogeneities within an test object. This change in the sonic waves makes a defect in the component detectable. This is why ultrasonics is used for crack detection, for example.
What can be seen when testing materials with ultrasonics?
Parameters relating to the number, size, shape or position of defects can be determined during a defect analysis with air-coupled ultrasonics. With these, the components to be examined can be easily classified according to OK and NOK parts (rejects).
Practical Application: Vulcanization of a Rubber Block

What are the Advantages of Material Testing with Ultrasonics?
The process is fast, reliable and cost-efficient and is particularly suitable for use in manufacturing companies where a quick check is required. It is also non-invasive, which means that it does not damage or affect the materials. In addition to defect and flaw analysis, air-coupled ultrasonics can be used to inspect adhesive bonds or welds.
Overall, material testing with ultrasonics is a valuable way of checking the integrity of materials and can help to identify and rectify quality problems at an early stage.
