Radiographic method – This is oldest and traditional approach to non-destructive testing. It is similar to X-ray testing and used to inspect the quality of the butt welds. In this method, penetrating radiation is absorbed to generate a high contrasting image indicating the cracks and discontinuities in the welds. Although this is an effective method but the high radiation can be harmful to the inspection crew and the public.
This method works on high-frequency sound waves to detect and size the defects in the welds. Advancement in this method made it automated which utilizes robotics to ensure complete coverage of the area under inspection and minimize human interaction (Badar 2008). It can easily locate surface and subsurface defects but requires high skills to operate the system.
Infrastructure Preservation Corporation (IPC) develops robotic nondestructive testing inspection services for infrastructure assets worldwide. Currently focused on transportation infrastructure, IPC’s technology can be used across infrastructure assets world over. We assure the safety of the inspection crew and the public during the inspection by using advanced and automated inspection systems under the supervision of experienced and certified personnel.
