Question: During a visual inspection of a multi-pass groove weld, you observe small, spherical voids scattered throughout the weld face. These voids are typically caused by trapped gases during solidification. What do these visual indicators point to?
Answer options:
- Slag inclusions ✅ Porosity
- Cracking
- Incomplete penetration
Correct answer: Porosity
Explanation: Porosity presents as small, spherical, or elongated voids within the weld metal, often visible on the surface, and is caused by trapped gases. Slag inclusions are non-metallic solids entrapped in the weld metal.
