在机车检修工作中,部件的无损探伤对保证检修质量和行车安全是非常重要的.目前在机车检修部门,由于从事这方面工作人员的操作技术和对他们的理论培训等存在许多问题,所以开展这方面工作的讨论是十分有益的. (一)目前几种主要探伤方法 1、电磁探伤电磁探伤的特点是适应性强,对被探部件要求不高,一般可吸磁的钢铁部件,不论是锻、铸件,还是机械加工的曲、直表面均能获
In locomotive maintenance work, the non-destructive testing of parts is of great importance to ensure the quality of maintenance and traffic safety.Now in the locomotive maintenance department, due to the staff involved in the operation of this technology and their theoretical training, there are many problems, so carry out Discussion of this work is very useful (A) of the several major testing methods 1, electromagnetic detection Electromagnetic detection is characterized by adaptability, less demanding on the member to be explored, the general magnetic parts can be sucked magnet, whether it is Forging, casting, or mechanical processing of the song, can get straight surface
