摘　　要：根据目前电阻点焊质量监控系统的目的,将现有技术分为对质量的评价和控制两大类。其中点焊质量评价技术主要有单参量监测技术和多参量监测技术,在点焊质量控制技术中,主要是通过监测焊接热量来控制和应用人工智能技术来实现。对在这两个研究领域中采用的不同分析手段,进一步进行了分析论述。在综合分析的基础上,指出选用合适的建模手段和分析方法,对质量评判指标实现准确测量,得出精确的结果是下一步工作的重点和难点。In this paper,according to the purpose of RSW （resistance spot welding） quality monitoring system,the existed technique for the RSW is classified into two categories：quality evaluation and quality control.The technology of single parameter and multiparameter is used in quality evaluation.and in the quality control,it is achieved by monitoring welding heat input and using artificial intelligent technique Based on the diverse method in the two categories,further analysis and discussion is done.At the end of this paper,it is pointed that in order to accomplish accurate measurements and obtain exact result,how to choose the qualifying method for modeling and analysis approach should be the emphasis and nodus for the next gradation.
