六十年代初,苏联首先将录磁探伤应用在石油管道焊缝的检查。其后,应用范围扩大到化工、电力部门的承压管道。1976年苏联国家标准已将这种方法正式列入国家检测手段。该方法不仅能记录工件表面缺陷的散射磁场,还可记录深度小于20mm部位缺陷的散射 In the early 1960s, the Soviet Union first applied magnetic recording inspection to the inspection of oil pipeline welds. Since then, the scope of application expanded to the chemical industry, power sector pressure pipelines. The national standard of the Soviet Union in 1976 has formally included this method in the national testing methods. The method can not only record the scattered magnetic field of the surface defects of the workpiece, but also record the scattering of defects with depth less than 20mm
