Visual examination is used to ___.

• A. Detect internal flaws
• B. Assess weld strength
• C. check for surface condition
• D. Evaluate material properties

Answer: (C)

Visual examination focuses on what you can see on the weld and surrounding surfaces. It is used to check surface condition—assessing cleanliness, bead shape and size, and the presence of surface defects like cracks, undercut, overlaps, or surface porosity. It cannot reveal hidden internal flaws or directly measure weld strength or material properties, which require other nondestructive tests or mechanical analyses.
