本文应用数理统计方法,首次给出CO_2电弧焊短路频率与电弧电压关系的函数解析表达式,并进行理论计算,得到的计算值与实验数据进行比较,其结果是令人满意的。文中所建的表达式,为CO_2电弧焊的研究和应用提供了理论依据。
In this paper, the analytic expression of the relationship between arc short-circuit frequency and arc voltage is given for the first time by mathematical statistics method. The theoretical calculation is carried out and the calculated value is compared with the experimental data. The result is satisfactory. The expressions built in this paper provide a theoretical basis for the research and application of CO_2 arc welding.
