Visual inspection is a method used to examine objects or surfaces for defects, damage, or irregularities. This process involves looking closely at the item without the use of specialized tools, relying instead on the inspector's eyesight. It is commonly used in various industries, including manufacturing, construction, and quality control, to ensure products meet specific standards. During a visual inspection, inspectors may look for issues such as cracks, corrosion, or misalignment. This technique is often the first step in identifying problems before more detailed testing is conducted. Effective visual inspection can help maintain the quality and safety of products and structures, such as bridges or machinery.
