Visual Testing Evaluation
Visual inspection evaluation is a systematic assessment of surface conditions, welds, or components with the naked eye or optical aids. It serves to detect external irregularities early before further testing.
Physicochemical mechanism of action
Visual inspection evaluation involves the visual inspection of surfaces and weld seams. No specific physical or chemical processes are considered, only the optical appearance of the surface.
Metallurgical relevance & risks in welding
Visual inspection evaluation is crucial for detecting external defects such as pores, cracks, or irregularities. Missing or inaccurate visual inspections can lead to later problems because minor defects are not detected and can be further enlarged.
Workshop practice & instructions
Use a clear, bright light beam for good visibility. Use optical aids such as a magnifying glass or microscope if needed. Record all visible defects in detail. Watch for pores, cracks, irregularities, and uneven color tones. Always perform the visual inspection before further testing.
