Surface Methods
Visual inspection of a weld using a flashlight and measurement tools.
Overview
Visual inspection is often the first and most fundamental NDE method. Qualified technicians examine welds, surfaces, and assemblies for discontinuities, dimensional issues, and workmanship using direct viewing or optical aids. Results support fabrication acceptance, in-service condition assessment, and identification of areas requiring further NDE.
Applications
- Weld visual examination (fabrication and in-service)
- General condition assessment of piping, vessels, and structural items
- Support for tank, vessel, and piping inspection programs
- Pre- and post-cleaning verification
