Visual Inspection (VT) Services in Tennessee
Visual Testing (VT) is the first and most essential step in any non-destructive testing process. At Tennessee NDT, we deliver thorough visual inspections using both unaided and enhanced optical methods to identify surface flaws, weld discontinuities, alignment issues, and signs of material degradation before they escalate into failures.
What Our Visual Inspection Services Include
- Direct Visual Testing (DVT): Performed with the naked eye or basic tools like flashlights and mirrors to inspect visible surfaces, joints, and welds.
- Enhanced Visual Testing: Utilizes magnifiers, borescopes, videoscopes, and lighting to detect fine surface flaws in hard-to-reach or enclosed areas.
- Weld Inspection & Joint Alignment Verification: We inspect weld beads, joints, and base materials for cracks, undercuts, spatter, overlap, and porosity based on ASME, AWS, and other standards.
- Corrosion & Coating Evaluation: Assess corrosion buildup, paint damage, and protective coating integrity for piping, pressure vessels, and structural components.
- Digital Visual Reporting: Clear documentation with high-resolution photos, annotated reports, and pass/fail summaries for audit and compliance needs.
- All inspections follow standards such as ASTM E165, ASME Section V, and AWS D1.1.
