摘要: 针对变速送丝调节系统脉冲埋弧焊的特点,利用MATLAB/SIMULINK软件对其动态过程进行了研究,建立了主电路仿真模型、电弧负载系统仿真模型及弧长变化系统仿真模型,并在此基础上形成了系统的整体仿真模型。仿真结果与实测波形吻合良好,证明了所建模型的正确性,并为脉冲埋弧焊的推广应用奠定了基础。

Abstract: Aiming at the characteristic of pulse submerged arc welding process with change wire-feed system,the simuloting model was developed by the software of MATLAB/SIMULINK which consists of the main circuit simulation model,arc load system simulation model and arc changing system simulation model.The experimental waveform is consistent with the simulating result,which validates the correctness of the model and lies the foundation of application of pulse submerged-arc welding process.
