摘　　要：:针对CO2 短路过渡气体保护焊的电弧特点 ,利用统计方法从电弧电压、电流中提取幅值和时域的 6个统计参数 ,作为焊接质量的评价依据。同时 ,针对CO2 气体保护焊常见的飞溅大和成型差等问题 ,设定焊接质量参数W ,并将神经网络技术引入质量评价系统 ,以求建立统计参数和质量参数之间的关系模型。通过实验 ,以神经网络估测的质量参数值W作为焊接生产过程质量控制的质量指标 ,绘制了中位数—极差控制图来实现对焊接过程的质量管理 ,初步构建了CO2According to the characteristics of the short circuit transfer in CO 2 gas shielded welding, six evaluation parameters are selected from arc voltage and current as statistic data. The neural network technology is used in this quality evaluation system to constitute the relation model between the statistic parameters and the quality parameter ‘W’that is designed aiming at spatter and imperfect weld.In order to control the welding process quality, the X～R fig is drawn after experiments with the ‘W’as the target aim of quality control and then the quality control system for CO 2 gas shielded weld is completed primarily.
