Arc welding is an important unit operation, widely used for joining parts into assemblies. It is desirable that it be automated, not in the sense of "unattended" (because of fire hazard), but in the sense of "aid to the operator" (helping him to be more productive). In this work additional information will be extracted from arcs for the purpose of insuring weld quality. The approach requires performance of nine tasks: modeling of electrical arc welding signals, data acquisition, signal analysis based on first-order statistical measures, signal analysis based on second-order statistical measures, signal analysis based on waveform features, effect analysis--correlation of direct weld defects with signal measures, casual analysis--correlation of weld defect causes with signal measures, microcomputer implementation, and real-time feedback control.

电弧焊是一种重要的单元操作，广泛用于连接 部件组装。 最好是自动化，而不是在 “无人看管”的意义（因为火灾危险），但在这个意义上， “对操作员的帮助”（帮助他提高生产力）。 在这 工作附加信息将从弧提取的目的 确保焊接质量。 该方法要求性能达到9 任务：电弧焊信号建模，数据采集， 基于一阶统计测量的信号分析 基于二阶统计测量的分析，信号分析 基于波形特征，效果分析--直接焊接的相关性 缺陷与信号测量，因果分析--焊缝相关性 缺陷原因与信号测量、微机实现，以及 实时反馈控制
