一、前言以电极间电压为动态参数进行点焊过程质量监控,具有参数单一、检测方便和精确可靠等优点。其前提条件是已知电极间电压在焊接过程中的变化规律。由于焊接时间较短,要找出这种规律,用常规方法检测和分析动态电极间电压是较为困难的。利用微计算机构成的数据采集处理系统,则简单易行。本文
I. INTRODUCTION The quality control of spot welding process takes the dynamic voltage between electrodes as parameters, with the advantages of single parameter, convenient and accurate detection. The precondition is that the variation of the voltage between the electrodes in the welding process is known. Due to the short welding time, to find out the law, it is difficult to detect and analyze the voltage between dynamic electrodes by the conventional method. The use of micro-computer data acquisition and processing system, it is simple and easy. This article
