Control of weld seams and welded connections

Imaging and quality control of welding seams

Non-destructive testing of welded joints


Function and application

A non-destructive test of welded connections / weld seams is achieved with the help of magneto-optics. In order to achieve a perfect welding result in terms of the best, desired properties, an accurate weld seam is necessary. For the quality of a weld, its homogeneity is of great importance. This means that all defects in the weld seam must be recognized and classified according to whether they have a negative impact on the welding result or not.

While ultrasound examinations are very time-consuming and expensive, our magneto-optical devices such as the cmos-magview are able to visualize a two-dimensional image of the magnetically readable information of the weld seam in real time. This happens either through the self-emitted field of the welded piece or through an externally applied magnetic field. The result of the magneto-optical analysis is a real image of the surface characteristics of the object to be tested.
