摘要
为了研究金属材料探伤仪器缺陷定位的准确度,阐述了斜探头前沿长度b值的3种测定方法。通过分析和判定,认为多点法测量的准确度高于二点法,一点法的测定误差最大。
In order to study the accuracy for defectometer to locatc the defects, three kinds of methods of taeasuring front distance, that is b value, of angle sensor were discussed. It is believed that the accuracy obtained by multi - points measuring method is higher than that of two - points method, in addition, the accuracy of one - point method is the lowest.
