摘要
在分析CO_2气体保护焊过程中电弧动特性的基础上,提出了焊接回路时间常数τ和短路电流峰值与焊接电流之比(I_(sd)/I_f),可以作为衡量整流器式CO_2气体保护焊电源动特性的指标。
Based on arc dynamic load characteristics in CO_2 gas shielded welding process, the time constant of welding circuit current and welding current are given, which are considered to measure the dynamic characteristic index of the rectifier-type CO_2 gas shielded welding power source.
