摘　　要：为了科学地评价焊接过程稳定性,利用汉诺威分析仪对埋弧焊电信号进行了测试,并分析统计结果。分析结果表明:可以利用电信号概率密度分布曲线的形状对焊接过程稳定性做出定性评价,曲线越集中,焊接过程越稳定;也可以利用基于电信号变异系数提出的焊接稳定系数对焊接过程做出定量评价,焊接稳定系数越大,焊接过程越稳定。In order to evaluate the stability of welding process scientifically ,the welding electrical signals of submerged are welding were tested using Analysator Hannover,and the statistical data were analyzed. The analysis results show that the probability density distribution curves ca,, be used to qualitatively evaluate the welding process stability, the more centralized the curve ,the more stable the welding process is. Welding stability coefficient is proposed basing on variation coefficient of the electrical signals ,which can be used to quantitatively evaluate the welding process stability, the bigger the welding stability coefficient, the higher the welding process stability is.
