Productivity increase leads to higher customer satisfaction, faster throughput times and greater profitability. In industry, for example, this can be achieved through improved workflows, processes or shorter walking distances. However, one of the most essential elements to increase productivity is to use the suitable manufacturing technology and invest in the right technical equipment.

The PRC7000 resistance welding control system from Bosch Rexroth takes the latest approaches with AI-supported process optimization, fast commissioning, state-of-the-art process controls, and quality monitoring systems, and can therefore be an essential element in increasing the productivity of your manufacturing.

New material combinations, higher expectations of quality and productivity, new plant technologies and fewer and fewer skilled workers. Bosch Rexroth addresses the problem by making the welding process as easy as pressing a play button. We help you with the simple search for the right welding parameters, the transfer to adaptive control and the automated search for the right monitoring limits. 

Industry demands adaptable solutions that support connectivity and consistency. That is why a welding control system needs Industry 4.0 capability. Welding generates immense amounts of data, which form the basis for predictive maintenance or process optimization with the help of machine learning, for example. Data must be collected, analyzed, and processed. Bosch Rexroth offers various solutions for this. With the IoT Connector, users can process the collected data, which they receive via MQTT or OPC-UA protocol, according to their needs and, for example, implement automatic logging for quality assurance. Bosch Rexroth also offers the Weld Spot Analytics – Insights solution. Collected data is used and processed with the help of domain-specific knowledge. Optimizations and the quick detection of inefficiencies are thus become even easier.

The position signal of the welding gun provides the most reliable information about the sequence of the welding process. Bosch Rexroth has taken precisely this approach with the Adaptive Position Regulation function and implemented it in the PRC7000 welding control system on the basis of the proven adaptive UI control. In addition, the control of the gun movement was also transferred from the robot to the control system – so it controls the process from the closing of the gun to the cooling of the welding spot.

The Adaptive Position Regulation combines the electrical with the mechanical process quantities and thus achieves a significant improvement in the weld spot quality. For any material and any material mix.

Energy-saving systems are becoming increasingly important in all areas of automotive production, including the energy-intensive chassis shop. The welding control generation PRC7000 from Bosch Rexroth was specifically designed to be energy-efficient and, for example, operates in standby mode with approximately 60 % less energy consumption than the previous generation. In addition to the standard variant in AC technology, the control is also available as a DC variant for optimized power consumption.

The scalable CNC system MTX creates the perfect basis for machine manufacturers and users to meet the increasing requirements in the field of beam cutting. When the MTX CNC system with integrated PLC meets the compact drive system ctrlX DRIVE, top performance in beam cutting is pre-programmed. Through the use of leapfrog or frog jump, splines, the high-performance CNC system and appropriate drive functions, users can beam-cut a reference metal sheet 10 to 15 percent more quickly than before.
