Which of the following is NOT typically looked for as a visual defect during VT?

Explanation:
Visual testing looks for surface defects on welds. A smooth, defect-free finish is not a defect at all—it's the quality you want to achieve—so it isn’t something you’d identify as a defect during VT. In contrast, porosity, cracks, and lack of fusion are the kinds of surface discontinuities VT is used to reveal, since they indicate improper welding that can compromise strength or integrity. Porosity appears as surface pits or voids, cracks are visible fractures, and lack of fusion shows incomplete bonding at the weld joint.
