Krautkrämer SpotVision

Phased Array Inspection of Spot Welds

With increasing vehicle production, the automotive industry is turning to image-based inspection to reduce downtime while maintaining high quality standards.



Spot weld inspection starts here

Waygate Technologies' Krautkrämer SpotVision, developed in collaboration with automotive manufacturers, is thefastest, easiest, and most accurate phased array solution for spot weld inspection. It provides confidence, parts are properly welded. Thisincreases productivityas well asensures product safety and that quality standards are met at all times.

Highlights


Benefits

Krautkrämer SpotVision Features
An industry first

The solution combines a phased array probe and the Mentor UT phased array flaw detector for comprehensive insights at the highest level. One of the most remarkable features of thenewly developed 2D matrix phased array probe is its flexible delay line, filled with liquid. This allows it to adapt to the overall complex geometry of spot welds. The flexible probe also providesoptimal acoustic coupling, avoiding false negatives and minimizing process delays.

Better insights allow for better results

The 2D matrix probe is combined withTotal Focusing Method (TFM) imaging technique. This achieves higher resolution and measurement accuracy than with a comparable phased array. Thanks to TFM, each element is fired individually and sequentially while all elements are listening.

Lower costs through increased confidence

Krautkrämer SpotVision is easy to set up and operate,reducing the need for trainingfor qualified inspection personnel. This is due to the software'sintuitive user interface. In addition, Mentor PC Live software connects the instrument to a PC via Ethernet, which is especially helpful when the operator is in a different location.

Product-related FAQs
What is TFM?

TFM is short for Total Focusing Method. In brief, each element is fired individually and sequentially, while all elements are listening. So the image reproduction is not limited by the number of pre-defined focal laws. With the TFM image processing, a higher resolution and measurement accuracy with a comparable phased array is achieved.

What are the benefits of a flexible versus a solid delay line probe?

With a flexible delay line, less couplant would be required for optimal acoustic coupling and the probe adapts easily to uneven surfaces, like spot weld indentations. As a result, false negatives are avoided.

Can I use the Krautkrämer SpotVision system for other applications than spot weld inspection?

Yes, you can. SpotVisionisused in combination withMentor UT, a multi-application phased array device. In the automotive industry, also theBond Scannersolution to inspect adhesive bonding can be used.

What is the accuracy of SpotVision?

For nuggets in the diameter range of 2.0 - 6.0mm, the measurement accuracy is ±0.5 mm / ±20 mil with a certainty of 90% according to VDA5 – Gauge R&R Analyses.
