Bosch Rexroth’s introduction of adaptive control in 2012 advanced the quality and efficiency of robotic resistance welding. Using cutting-edge hardware and software, adaptive control monitors various process parameters to perfect each weld. The system samples weld parameters on a millisecond basis, compares them in real-time against a master resistance curve, and automatically adjusts the process to ensure consistent, quality welds.
However, recent trends in the automotive industry, such as lightweighting and electrification, presented challenges for this technology. As a result, Bosch Rexroth has developed more sophisticated adaptive resistance control systems that incorporate advanced software and dual-processor architecture.
