| Abstract: | Droplet transfer and its arc behavior in CO2 arc welding with small diameter wire were studied by experiments. Stability and scatter extent of the arc welding process were analyzed. Statistics laws and two-dimension stable region of the influence of arc voltage and current on the frequency of short-circuit droplet transition were obtained. Based on these,the primary elected arc voltage recommendation value corresponding to a given current can be ascertained,and a primary welding state of optimizing control of the droplet transfer can be set up. This method can be used to analyze and evaluate the stability and the scatter extent of the droplet short-circuit transfer,as well as good or bad of arc behavior of CO2 arc welding process relatively. |
