Innovations in welding technology: The power of ARC-EYE Adaptive Multi-Pass

In the world of welding, precision and efficiency are of utmost importance. The ARC-EYE Adaptive Multi-Pass application offers a solution to the challenges associated with labour-intensive welding processes for thick plate materials with varying weld seams. Especially in heavy industries, we often see large variations in weld seams between plate materials, making automation seem impossible at first glance. However, with ARC-EYE Adaptive Multi-Pass, this is now changing.

ARC-EYE is the basis

The ARC-EYE technology is designed to increase the accuracy of welding processes by using advanced camera and scanning techniques. The basis for this technology is the ARC-EYE laser sensor camera from Valk Welding. The basic functionality of the ARC-EYE camera is to follow the pre-programmed weld seam in real-time in both position and orientation. By adding the Adaptive plug-in, it is possible to correct the welding parameters in real-time while following the weld seam when deviations in the geometry of the plate material occur. This applies not only to welding current and voltage but also to welding speeds, oscillation movements, and any waiting times.

ARC-EYE Adaptive Multi-Pass

With the advent of the Adaptive Multi-Pass application, the ARC-EYE camera goes a step further and can now make automated calculations to achieve optimal filling of the weld seam. First, the ARC-EYE scans the programmed weld line and creates a 3D landscape based on the scan. Additionally, the Adaptive Multi-Pass application is fed with a knowledge base containing all the properties of the material to be welded. This information is combined by the Adaptive Multi-Pass application to determine the correct welding parameters. The multi-Pass application calculates how many layers and weld lines are needed to fully fill the weld seam and which welding parameters should be used. This not only guarantees welding quality but also brings significant economic benefits by reducing the consumption of welding wire and saving a lot of time both during and after welding, where excess weld material would otherwise need to be ground away. An important aspect of using the ARC-EYE Adaptive Multi-Pass application is the knowledge base from which the software makes the right choices for optimal welding. This knowledge base, which users can easily fill themselves, contains all the data of the material to be welded under various (welding) conditions. Based on a few welding tests, the behaviour of the material is analysed, after which the software calculates all intermediate values for all possible situations. So, you keep your own welding knowledge in-house!

Self-steering

Once the ARC-EYE has created the 3D landscape and the knowledge base contains all the data, the Adaptive Multi-Pass calculates the required welding parameters and how the weld can be optimally laid. For example, in the case of a 4mm weld, the software knows exactly which parameters to use to optimally lay the weld with that type of welding wire. In the case of varying depth and width, as seen with a V-groove, the ARC-EYE Adaptive Multi-Pass goes a step further and calculates how many layers the weld seam should consist of. If the width then deviates too much, the software calculates whether two weld lines next to each other can ensure an optimal end result.

Conclusion

The new Valk Welding ARC-EYE Adaptive Multi-Pass development, like other unique developments from Valk Welding, will once again push the boundaries. In combination with the exceptionally reliable and flexible Valk Welding robot installations, this development will be a real game changer for bridge construction, shipbuilding, offshore, wind energy, excavators, and the transport industry.
