Visual examination is a form of nondestructive testing.

• A. True
• B. False
• C. Sometimes destructive
• D. Not applicable

Answer: (A)

Visual examination checks a part’s surface condition using the naked eye or simple aids like a flashlight, mirrors, or magnifiers. It is nondestructive because nothing is cut, heated, or otherwise altered in a way that damages the component, so it does not affect the part’s integrity. This makes it a fundamental NDT method for spotting surface defects such as cracks, porosity, misalignment, corrosion, or weld flaws without causing harm. Keep in mind it mainly reveals surface conditions and may miss subsurface issues, which is why it’s often combined with other NDT techniques. The statement is true and the method is a standard part of welding and joining inspections. The other options don’t fit because visual examination does not destroy the part, is applicable as a basic NDT, and is not described as destructive.
