摘　　要：采用VisualC++开发了一套信号采集、信号处理、实时显示的焊接电信号测试分析软件。该软件具有界面友好,简单易用的特点,包含了统计、微分等多种模块。利用这些模块可对CO2气保焊的熔滴过渡电弧特性进行分析,从而提取有价值的焊接电弧特征信息。This paper designs a welding arc information testing and pr oc essing system,which can deal with data acquisition,signal processing and real-time display in Visual C ++ .The system has a friend by interface and is very easy to use.It contains filter analysis and differential analysis,etc.By these functions,the arc cha racter of the CO 2 droplet transfer welding process can be analyzed so as to extract more valua ble information.

关 键 词：实时显示 信号处理 电弧特性 多线程
