Mathematical Model and Simulation on Dynamic Process of Droplet Short Circuiting Transfer

It is a difficult task to study the many controll parameters of waveform control method.In order to solve this problem,a methematical model of the droplet short circuiting transfer dynamic process in CO₂ gas shielded arc welding is established.The developed model is converted into Simulink simulation model in software MATLAB and simulation of it is also made.Finally,to prove it,many experiments are conducted.The result indicates that the developed way of model is reasonable and the model is practicable.It also shows that the software MATLAB is a workable tool for the dynamic process of droplet short circuiting transfer.
