【Abstract】 The paper gives the block diagram of submerged arc welding inverter power supply control system and process control system.Control algorithm is determined. Calculation steps are given.Two piece of STM32F103VBT6 single-chip microcomputer are used as main control chip. Double closed-loop control is used to complete the submerged arc welding inverter power supply output features. Single closed-loop control is used to complete the walking motor speed control.Double closed-loop control is used to complete the wire feeding motor speed Control.Experimental data show that the system is stable and reliable. The system has practical value.更多还原
