Question: A welder is visually inspecting a fillet weld on a structural steel component. The weld appears to have an uneven surface with irregular ripples and inconsistent bead width. What is the most likely visual discontinuity present?
Answer options:
- Undercut
- Porosity
- Incomplete fusion ✅ Irregular weld bead
Correct answer: Irregular weld bead
Explanation: An uneven surface with irregular ripples and inconsistent bead width is a direct visual indication of an irregular weld bead. Undercut is a groove in the base metal, porosity appears as small holes, and incomplete fusion is a lack of coalescence, none of which are primarily characterized by surface unevenness and inconsistent bead shape.
