Our welding systems make you fit for the future

Bosch Rexroth is an innovation driver and role model in the global welding industry – and has been for over 60 years. In addition to our outstanding engineering skills, our pioneering role also constantly challenges us to make our technologies compatible with the requirements of the Factory of the Future. With integrated IoT interfaces, AI-enabled hardware components and web-based control solutions, we are setting the course for a seamless transition into the future.

We offer you a comprehensive solution

What makes an excellent resistance spot welding range? It is wide-ranging and offers versatile software and hardware solutions from a single source – or just the exact components that are needed. This is also reflected in our own range: It is freely scalable and thus enables both customized and pragmatic system solutions. Our many years of experience, which we have gained in cooperation with various industries, make us a unique supplier of welding technology on the market and coherently round off our range of products.

Our strength, your gain: adaptability

Adaptability is the core competence when it comes to evolving with the ever-changing demands of the industry and individual sectors such as the automotive industry. The joy of change and transformability is not only reflected in our attitude, but also in the characteristics of the technologies and processes; be it adaptive controls, real-time quality monitoring or web-based engineering tools – to name just a few aspects.

Intuitive operation. Reduced costs.

Increased complexity and requirements in resistance welding meet a shortage of skilled workers. The welding control system PRC7000 makes welding simple – even for untrained users. The Functional Bundle "Simplicity" provides components such as PRIweb" and "Auto Reference Curve Creation".

The web-based user interface "PRIweb" stands for simple and intuitive usability. It thus offers advantages over the classic PRI7000, especially for unskilled users. The function is designed for use on mobile devices such as tablets. Users are provided with an intuitive user interface that allows them to quickly find and operate special functions, for example.

The "Auto Reference Curve Creation" function addresses two important capabilities of the welding control PRC7000: adaptive control and monitoring. For these, control curves must initially be recorded and activated. Until now, this required a high level of domain knowledge. This process can now be automated, which reduces the effort and ideally improves the result.

Less spatter. Highest productivity.

Resistance welding in record time. The "Dynamic Squeeze Time" and "Adaptive Spatter Reduction" software components, which are part of the "Productivity" license package, simplify resistance welding – for example in automotive production. The result: higher productivity, quality optimization and reduced workload for users.

"Dynamic Squeeze Time" reduces the hold-off time depending on force and position. The feature can only be used in conjunction with the integrated gun control. Overall, this results in reduced hold-off time and increased productivity by shortening the production process.

"Adaptive Spatter Reduction" also focuses on savings and supports weld parameter optimization during the commissioning phase and series production of the car. Welding parameters are automatically optimized in terms of quality and spatter rate as well as energy efficiency and limit values. For example, weld spatter occurring during the welding process can be automatically detected and minimized within a predefined tolerance band.

Artificial Intelligence. Real future opportunities.

The welding control system of the future is intelligent and draws benefits from the data generated in the welding process. This data can form the basis for process optimization and value creation in Industry 4.0 – for example, through self-learning processes and predictive maintenance. To do this, they must be collected, analyzed and processed. With the "IoT Connector" from Bosch Rexroth, users can easily collect data treasures, process them according to their needs, and implement automatic logging for quality assurance, for example.

More service. Less downtime.

Where does good service start and where does it end? Ideally, it accompanies the entire life of a welding control system – and beyond. The Bosch Rexroth service portfolio for resistance welding ranges from commissioning through to the second life of a product. In addition to various services for optimizing the welding process, the services for the entire life cycle also enable a longer product life of the welding control system as well as resource conservation. For example, used control units are given a new lease of life through remanufacturing.

With its welding services, Bosch Rexroth is breaking new ground in the industry. Until now, the focus in welding technology has often been on the hardware. But it is the services that make welding control systems fit for the challenges of today and tomorrow.
