Direct Visual Testing
Direct visual inspection involves visually inspecting a component with the eye or optical aids when the surface is accessible.
Physical-Chemical Mechanism of Action
Visual inspection directly allows surface flaws, cracks, deformations, and other anomalies to be detected. No special light or special equipment is needed, just the naked eye or simple optical aids like a magnifying glass.
Metallurgical Relevance & Risks in Welding
Incorrect visual inspection can lead to inaccurate results. It is important to thoroughly check the surface and carefully document all potential defects. Missing a defect can lead to later failures or safety issues.
Workshop Practice & Instructions
Use a magnifying glass with at least 10x magnification for detailed inspection. Make sure the surface is clean and free of dirt to ensure a clear view. Document all found defects in a log with photos or sketches.
