当射线检测发现零件存在超出使用性能要求的缺陷时,需要排除缺陷。排除缺陷造成的挖补和修理区域应尽可能的小,以减小应力和对材料组织性能的改变。这就需要在修补前确定缺陷的深度。常规的射线检测获得的是零件的二维投影信息,无法判断缺陷的深度,通过对二次平移透照法的研究,探索这种方法的可行性,并从理论和试验两个方面提出方法的改进,以减少相应的误差,为实际检测提供参考。
When the ray inspection found that the existence of parts beyond the performance requirements of the defects, the need to rule out defects. Exclusion and repair of defects caused by the area should be as small as possible to reduce the stress and the material properties of the organization change. This requires determining the depth of the defect before patching. Routine ray detection is the two-dimensional projection of the part information, can not determine the depth of the defect, through the study of the second translation transillumination method to explore the feasibility of this method, and from the theoretical and experimental aspects of the proposed method Improve to reduce the corresponding error, provide a reference for the actual test.
