【摘要】 动态多参数实时监测是电阻点焊质量在线评估的一种有效方法。采用VisualBasic6.0语言编程,通过80C196KB和PC机之间的串行通信,实现了对焊接电流和电极压力的实时检测,联机试验所生成的波形图实时反映了三相次级整流点焊的动态焊接过程以及曲线变化趋势与影响因素之间的对应关系,为点焊质量多参数监控奠定了基础。更多还原

【Abstract】 Multi-parameters graphic display of spot welding dynamic process is an effective way for online welding quality estimation.This article introduces the real-time inspection of welding current and electrode pressure with VB6.0 and through serial communication between personal computer and microcomputer.These waveforms directly reflect the dynamic process and the corresponding relationship between curves change trend and influence factors,which establish a base for multi-parameters quality control of spot welding.更多还原
