TESTING APPLICATIONS FOR AIR-COUPLED ULTRASONICS
Non-destructive & coupling agent-free ultrasonic testing
Adhesive bonds are becoming increasingly common in modern production processes because they offer numerous advantages. In the automotive industry, for example, adhesive bonds make car bodies lighter and increase their structural rigidity.
However, the implementation of good bondings is increasingly challenging. Because they tend to leak and require a clean, grease-free, dry and well-tempered environment, bonded joints should be tested. However, in practice there are only a few non-destructive testing methods that are suitable. Air- coupled ultrasonic testing with the yoUSan system is a proven method for this challenge.
Defect & Flaw Analysis
The main advantage of defect analysis with air-coupled ultrasonic is the fast detection of cracks, inclusions, pores and blowholes in the production line. Ultrasonics can detect and visualise the change between air and material particularly well. This makes the various inspection applications in the field of defect analysis easy to manage for air-coupled ultrasonics.
Welded, Brazed & Soldered Joints
The stability of plastic welds , spot welds or soldered joints can be analysed regarding their quality using air-coupled ultrasonics via two different procedures we offer.
With ultrasonics, it is possible to automatically inspect the weld bead for cracks or holes. The uniformity of the waves, width and height of the weld bead can also be assessed. An inspection for weld penetration is also feasible. The evaluation of these parameters is important for assessing the strength of the weld and stiffness of the entire component.
