摘　　要：点焊过程电信号分析系统是研制高质量焊接设备的一种重要测试技术手段。基于Win-dows环境、高速数据采集卡PCL1800和工控机通用平台,采用Visual C++6.0开发出高速多功能点焊过程电信号测试分析软件。该系统能精确测定点焊过程的电极间电压和焊接电流波形,并提取出焊接过程动特性的特征信息,从而为高性能焊机的研制和焊接参数的优化提供了一个强有力的工具。Analyzing system of electric signals in spot welding process is a very important detecting instrument for developing high quality welding equipment. Based on general platform with Windows operation circumstance ,high speed data acquisition card PCL1800,and industrial computer. A software for detecting and analyzing electric signals in spot welding process with high speed and multifunction has been developed by using Visual C＋＋6.0. The system can detect current and voltage waveform of spot welding process, and extract dynamic characteristic information of spot welding process. Thus ,it provides a powerful tool for developing high performance welding and optimizing parameters in spot welding process.
