摘要
对标称K值为2的探头,检测缺陷已知的钢板对接焊缝,在仪器输入的K值距测量的实际K值间有不同偏差的情况下,分别得出缺陷测量结果,分析了K值偏差对缺陷定位定量相关参数的影响程度,对参加超声检测二级考试学员的疑问得出了确切的回答,K值测量时产生的正负0.04范围内的误差不影响最终成绩,可以作为考级人员K值测量的参考。
Using nominal Kvalue of 2to detect the given flaw of steel plant butt weld,the location and quantity parameter of the flaw in the case of inputting different Kvalue with deviations were acquired.How the K value deviation was to affect the detection result was analyzed and questions by the candidates were answered.Deviation of±0.04for the Kvalue shall not affect the grade of students and it will be a reference to candidates only.
