Waygate Technologies' Krautkrämer SpotVision, developed in collaboration with automotive manufacturers, is the fastest, easiest, and most accurate phased array solution for spot weld inspection. It provides confidence, parts are properly welded. This increases productivity as well as ensures product safety and that quality standards are met at all times.
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 the newly 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 provides optimal acoustic coupling, avoiding false negatives and minimizing process delays.
Better insights allow for better results
The 2D matrix probe is combined with Total 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 training for qualified inspection personnel. This is due to the software's intuitive 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.

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. SpotVision is used in combination with Mentor UT, a multi-application phased array device. In the automotive industry, also the Bond Scanner solution 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.
