Together with welding specialist Fronius, VITRONIC is launching its latest innovation Weldloop. The software solution helps vehicle manufacturers optimize their welding lines faster and reduce rejections. With Weldloop, inspection data and welding process data can be linked and displayed together for the first time. Thanks to the data correlations and special evaluation tools, the causes of defects can be identified and eliminated much faster than before. Weldloop is currently already being used by selected pilot customers, including a major automotive manufacturer.

Vehicle manufacturers must reconcile safety and economy

Bodywork, axles, battery boxes for electric cars: safety always comes first when it comes to welds for such critical vehicle parts. No defective weld seam must leave production. But errors happen. Car manufacturers and suppliers therefore make immense efforts to inspect every single weld seam and improve the welding processes. 

At the same time, they have to pay attention to profitability, increase plant availability and output, and minimize rejections. Until now, these goals have been difficult to reconcile: That's because the tasks surrounding weld inspection and process optimization are largely performed manually. 

Analyzing welding processes through data correlation

For this area, VITRONIC's Weldloop solution represents a real breakthrough. The prerequisite for its use is the VIRO WSI automatic inspection unit, which inspects each weld seam using 3D image processing and records the data. With the Weldloop software, inspection data from quality control can now be linked with data from the welding process.  

Engineers can use Weldloop to efficiently analyze large amounts of data and graphically display trends. This allows them to quickly identify deviations, as well as their possible causes and at which welding station they occurred. Without Weldloop, engineers would manually have to compare all the data and go through troubleshooting procedures. 

In this way, vehicle manufacturers can save significant costs. The downtimes of the welding lines are reduced. At the same time, they improve the quality of the welds and the inspection: this means fewer rejects and less effort for manual reworking. 

Jointly developed with technology leader Fronius

VITRONIC developed Weldloop in close cooperation with Austrian company Fronius, the global technology leader in robotic welding. The software was tested and further improved for months at selected pilot customers in the run-up to the market launch. A major automotive manufacturer is also already using Weldloop productively. Now Weldloop is available as a mature solution for all companies that use Fronius welding systems together with the Fronius data documentation solution WeldCube Premium. 

Weldloop is the gateway to automated process optimization for welding lines. Currently, the software merely links and analyzes the data. In the future, the welding line can be imagined as a "closed-loop system": It continuously evaluates data, optimizes itself and can intervene independently before errors occur. 


VITRONIC is the world's leading innovation driver for industrial image processing, enabling its customers to master the challenges of tomorrow.  

The owner-managed group of companies develops forward-looking solutions in the form of specialized products and software for image-based quality inspection, identification and process optimization, ​​which find application in the growth sectors of automation and traffic engineering. 

VITRONIC solutions make an important contribution to helping shape a safe and sustainable world. The existing limits of what is economically feasible are constantly being questioned in order to achieve the highest quality and productivity, for example in the production of automotive and pharmaceutical companies. Worldwide, Auto-ID solutions in logistics centers and at cargo airports, take over the reliable and efficient recording of shipments and thus ensure a transparent flow of goods.  

In the transport sector, VITRONIC offers leading technology for increased safety on the roads, for optimizing traffic flow and for recording road usage.  

Open and honest dealings with our customers form the foundation for jointly exploiting technological and process potential to the full. Joint success forms the basis of long-term cooperation with companies such as B. Braun, BMW, Daimler, DHL, UPS, Toll Collect, Fresenius and Sanofi as well as with public clients. 

Since its foundation in 1984, VITRONIC has been growing continuously for almost 40 years. The current annual turnover (2022) is 208 million EUR and the company is currently represented on five continents in over 80 countries with 1,400 employees.  

Development and production of VITRONIC systems are located at the company headquarters in Wiesbaden. VITRONIC subsidiaries span across all continents, including North and South America, Europe, Asia, Africa, and Oceania. Additionally, a global network of sales and service partners ensures localized support for international customers.
