Visual inspection is a technique that uses the human eye to identify defects in products or equipment. It can be done in person or remotely using digital images.

Visual inspection is a fundamental, inexpensive, and quick method of non-destructive testing (NDT). It’s often used as a preliminary step before more complex methods. However, it’s limited to detecting noticeable defects and doesn’t provide quantitative information about them.

Here are some tips for creating a visual inspection strategy:

Define the scope: Determine what needs to be examined, how, and why

Identify potential defects: Consider the types of defects or issues that might be present

Select an inspection technique: Choose a visual testing method based on the object, potential defects, and available resources

Establish criteria: Set clear and measurable criteria to determine if the object meets specifications

Develop a procedure: Create a detailed step-by-step procedure for the inspection

Train the team: Ensure the inspection team has the knowledge, skills, and resources to conduct the inspection

Review and update: Regularly review and update the inspection strategy to ensure it remains effective

Some visual inspection techniques include: Direct visual inspection, Microscopic inspection, Magnetic particle inspection, and Liquid penetrant inspection.
