Book cover Robotic Welding, Intelligence and Automation

Part of the book series: Lecture Notes in Control and Information Sciences ((LNCIS,volume 362))

Abstract

An intelligent waveform control system with micro-controller is developed for robotic high-speed CO2 arc welding. In order to resolve the problems of bad weld formation and heavy spatter in high-speed CO2 arc welding, A new method of welding current waveform control is investigated, which controls the short-circuit current and its rising rate in short-circuit period, and adopts the two-step constant current control to adjust the arc energy in arc period. The control principle of the method is discussed, the system structure and the control software are introduced, and the optimized waveform control parameters are provided by experiments. The results show that this system can precisely control the arc energy by the two-step constant current method and improves the performance of high-speed welding process obviously
