摘　　要：插销试验是评估金属材料焊接裂纹倾向的试验方法。为了提高该试验方法的可靠性、精度和自动化程度,研制了一个以PCL-818LS数据采集卡为核心的计算机辅助智控系统。通过大量冷裂纹和再热裂纹插销试验表明,整个系统的可靠性和精度能满足试验要求。Implant test is an experimental method to assess the cracking tendency of the weldability of metallic materials.In order to improve the reliability,precision and automatic degree of the test,a new computer aided control system has been done with PCL-818LS core.The results of the implant test which assesses the cold and reheat cracking sensibility of the quenched and tempered steel show that the reliability and the precision of the testing system meet the demand,and its automatic degree is improved largely.
