为了更直观地确定铁磁性材料内缺陷的位置以及形貌特征,本文在二维成像技术和解析延拓的基础上提出了应用于磁法检测的2(1/2)维成像。对预置有水平圆柱体状缺陷的Q235板材进行检测,实验结果表明:2(1/2)维成像可以体现缺陷的位置和形貌特征,实现了磁法检测结果的可视化,为检测人员进行缺陷的判定提供可靠依据。 In order to determine the position and the morphological characteristics of the defects in the ferromagnetic material more intuitively, this paper proposed 2 (1/2) -dimensional imaging which is applied to the magnetic detection based on the two-dimensional imaging technique and the analysis and extension. The results show that the 2 (1/2) -dimensional imaging can reflect the position and the topography of the defects and realize the visualization of the magnetic detection results for the inspectors The determination of defects provide a reliable basis.
