Visual inspection will usually reveal which of the following?

• A. All of the above
• B. Cracks
• C. Corrosion
• D. Scratches

Answer: (A)

Visual inspection focuses on surface conditions and is the quickest way to spot common defects. Cracks show up as visible lines or separations in the material; corrosion appears as rust, staining, pitting, or flaking of coatings; scratches appear as surface gouges or fine lines from wear or handling. These are all surface features that can usually be seen with good lighting and without tools, so you typically can detect all of them through a routine visual check. Keep in mind that some flaws, like subsurface cracks or corrosion beneath coatings, may require additional methods to reveal, but for what is usually visible by eye, cracks, corrosion, and scratches are the common findings. Therefore, the best answer is that all of these can be revealed by visual inspection.
