Discontinuities & Non-Destructive Examination

Test inspection decision-making under AWS quality criteria:

Metallurgy & Discontinuities Sample Question 1 of 1
During visual testing (VT) of a groove weld produced via FCAW on structural carbon steel, the inspector observes an elongated surface discontinuity with sharp tips running parallel to the weld bead within the heat-affected zone (HAZ). How must this condition be evaluated?
A
Acceptable clustered porosity if under 3 mm in diameter.
B
A longitudinal crack, classified as an automatic critical defect requiring immediate rejection and repair.
C
Root incomplete penetration permissible by structural design specifications.
D
Mild undercut that requires no corrective measures.
✓ Official Explanation: (B) Cracks feature sharp notches that create severe stress concentrations. Under AWS structural welding codes (such as AWS D1.1), any crack regardless of size is strictly prohibited, constituting an immediate cause for weld rejection.
