短路过渡型CO

弧焊系统在焊接过程中易产生飞溅，这主要是焊接过程中电弧能量不稳定和熔滴过渡状态不理想所致。为解决这一问题，从弧焊系统主电路结构出发，构建了全逆变和后级加入斩波两种不同控制方式的数学模型。在一定假设条件下，使用MATLAB中的Simulink模块建立两种控制方式的仿真模型，并对两种主电路结构下的输出波形进行对比分析。结果表明，后级加入斩波控制的主电路结构能更有效地满足CO

焊短路过渡低飞溅的需求。这种控制方式能够通过调节电弧能量和熔滴过渡状态，降低焊接过程中的飞溅，提高焊接质量。此外仿真结果还显示，后级加入斩波控制的主电路结构在降低飞溅的同时，还能够有效改善焊接过程的稳定性，提高焊接效率。这对于优化CO

弧焊系统的控制方式和提高焊接质量具有重要的理论意义和实际应用价值。
The short-circuit transition type CO
2
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 different 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 waveforms 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 CO
2
welding. This control method can reduce the spatter during the welding process and improve the welding quality by adjusting 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 CO

arc welding system and improving the welding quality.
