Abstract
The short-circuit transition type CO2 arc welding system is prone to spatter during the welding process,which is mainly due to the unstable arc energy and the undesirable transition state of the molten droplets during the welding process.In order to solve this problem,from the main circuit structure of the arc welding system,the mathematical model of two dif-ferent control modes,namely,full inverter and rear stage adding chopper,is established.Under certain assumptions,the simulation model of these two control modes was established using the Simulink module in MATLAB,and the output wave-forms under the two main circuit structures were compared and analyzed.The results show that the main circuit structure with chopper control in the back stage can more effectively meet the demand for low spatter in the short-circuit transition of CO2 welding.This control method can reduce the spatter during the welding process and improve the welding quality by ad-justing the arc energy and the transition state of the melt droplet.In addition,the simulation results also show that the main circuit structure of the latter stage to join the chopper control in the reduction of spatter at the same time,but also effectively improve the stability of the welding process,improve welding efficiency.This has important theoretical significance and practical application value for optimizing the control mode of CO2 arc welding system and improving the welding quality.关键词
