摘　　要：随着对电阻点焊质量要求的不断提高,现有的检验方法已不能满足低成本、高效率的现代化生产,因此,建立基于过程参数的电阻点焊质量评定系统非常必要。本文设计的应用于电阻点焊数据采集系统的电流传感器和电压传感器,以及与之配套的信号调理电路,完成积分和放大的功能。测试结果表明,所设计的信号调理电路符合设计要求,为开发电阻点焊质量评定系统提供了必不可少的硬件组成部分。With the constant improvement of resistant spot welding quality demands,the existing testing method can＇t measure the needs of low cost and high efficiency of modern production.So it is necessary to build up a resistant spot welding quality evaluation system which is based on process parameters.To design new current transducer and assorted signal processing circuit for resistant spot welding data acquisition system can complete the function of integral and amplify.The measured results indicate that the signal processing circuit meets the design requirements.Thus,it provides a powerful tool for developing high performance welding and optimizing parameters in spot welding process.
