Question: According to CSA W178.2, a visual inspection of a welded joint should primarily look for:
Answer options: ✅ Undercut, porosity, and incomplete fusion
- Hardness, tensile strength, and impact resistance
- Chemical composition, microstructure, and grain size
- Ductility, yield strength, and fatigue limit
Correct answer: Undercut, porosity, and incomplete fusion
Explanation: Visual inspection focuses on surface discontinuities and general weld quality. Undercut, porosity (if open to the surface), and incomplete fusion (if visible at the surface) are common defects detectable by visual examination.
