Purpose目的1.1. Conducting NDT test (including DPI and MPI tests), is to test nonconformities of welds such as cracks and holes etc. after welded and grinded, .对焊接打磨后焊缝进行探伤检测（包括渗透探伤和磁粉探伤测试），确保焊缝无裂纹，孔洞等不良。2. Applicable Scope适用范围 2.1. It is applicable to nonconformities of welds for all mould steel frame and the accessories.适用于所有焊接件焊缝打磨后不良检测。3. Responsibilities职责 3.1 Quality inspector is responsible to do NDT test (including DPI and MPI tests) after welding is finished and grinded, and make records.质检员负责对焊接打磨后的焊缝进行探伤测试(包括渗透探伤和磁粉探伤测试)，并作好记录。4. Equipment/Apparatus needed 所需设备: 4.1. DPI testCleaner, Penetrant, Developer清洗剂，渗透剂，显象剂4.2. MPI testMagnetic suspension liquid, Magnetic tester 黑油磁悬液， 磁轭探伤仪5. Procedures工作程序5.1 DPI test 渗透探伤测试 5.1.1Clean the surface to be inspected with cleaner and be dried.用清洗剂清洗待检焊缝表面，并干燥之5.1.2 Penetrant to be sprayed onto the surface and to be kept for 5 to 15 minutes.将渗透剂均匀喷涂于待检表面，并保持5-15分钟。5.1.3 Remove the excess penetrant with cleaner or water and wipe it dry用清洗剂或水清除多余渗透剂，并用干净布擦干。 5.1.4 Spray the developer, and visually check the welds. If the welds have defects such as cracks, the penetrant will be displayed. Then repair the bad welds.喷涂显像剂，并观察。如焊缝有裂纹等不良，渗透剂会显像出来。对不良焊缝要求修复。5.1.5 Record it with pictures. 使用图片进行记录.Spray developer/喷涂显像剂5.2 MPI test 磁粉探伤5.2.1 Connect on side of cable to the magnetic tester and the other side to power supply.将电源接头一段与磁粉探伤仪连接5.2.2 spray magnetic suspension liquid onto area to be inspected.向被检区域喷洒磁悬液。5.2.3 deposit the prober arms on the area to be inspected, and keep in good touch, then press the switch button, keep for 2-3 seconds将探头关节开面放置在被检工件上，保持良好接触，按下探头开关，保持2-3s。 5.2.4 Loosen the switch button, and remove the prober arms, then visually check, if the welds have defects such as cracks or holes, then the magnetic powder will congregate on the surface of cracks. Repair the bad welds 松开探头开关，移开探头，并观察。如焊缝有裂纹等不良，磁粉会聚集在裂纹表面。对不良焊缝要求修复。5.2.5 Record it with pictures. 使用图片进行记录.6.
