,Q1 DEMONSTRATE MASTERY OF CORE CONCEPTS
During visual inspection of a completed groove weld, you observe a surface
discontinuity that appears as a shallow depression at the weld toe. According to
CSA W59, which acceptance criterion applies, and what is the maximum permitted
depth for a weld less than 12 mm thick?
A. It is a crack and is unacceptable regardless of depth.
B. It is undercut and must not exceed 1 mm depth. CORRECT
C. It is a crater and must be repaired if deeper than 0.5 mm.
D. It is a slag inclusion and must be removed completely.
RATIONALE: Undercut at the weld toe is a common surface discontinuity. CSA W59 limits
undercut depth to 1 mm for welds less than 12 mm thick, and to 1.5 mm for thicker welds. Cracks
are always unacceptable, but the description points to undercut, not a crack. Crater and slag
inclusion have different characteristics and criteria.
Q2 DEMONSTRATE MASTERY OF CORE CONCEPTS
In a fillet weld, the theoretical throat is calculated as 0.707 times the leg size for a
45-degree isosceles triangle. However, when the weld profile is convex, the
effective throat may be less than the theoretical throat. Which of the following best
explains the impact on the weld's load-carrying capacity?
A. The effective throat is measured perpendicular to the weld face, and convexity increases it, so
capacity increases.
B. The effective throat is the shortest distance from the root to the weld face, and excessive
convexity reduces this distance, decreasing capacity. CORRECT
C. The effective throat is determined by the leg size only, so convexity has no effect on capacity.
D. The effective throat is always larger than the theoretical throat, so capacity is always higher.
RATIONALE: The effective throat is the minimum distance from the root to the weld face.
Excessive convexity can cause the weld face to bulge, but the shortest distance may still be less
than the theoretical throat if the profile is not a perfect isosceles triangle. This reduces the
effective cross-section and load-carrying capacity. Leg size alone does not account for profile
variations.

,Q3 DEMONSTRATE MASTERY OF CORE CONCEPTS
A visual weld inspector is evaluating a fillet weld that connects a 10 mm thick plate
to a 20 mm thick plate. The weld leg sizes are 8 mm on the horizontal member and
6 mm on the vertical member. According to AWS D1.1, what is the minimum
required fillet weld size based on the thicker member, and does this weld meet the
requirement?
A. Minimum size is 6 mm; the weld meets the requirement because both legs are at least 6 mm.
B. Minimum size is 8 mm; the weld does not meet the requirement because the vertical leg is 6
mm. CORRECT
C. Minimum size is 6 mm; the weld does not meet the requirement because the horizontal leg is
8 mm.
D. Minimum size is 10 mm; the weld does not meet the requirement because both legs are less
than 10 mm.
RATIONALE: AWS D1.1 specifies minimum fillet weld sizes based on the thicker of the two
members joined. For a thicker member of 20 mm, the minimum fillet weld size is 8 mm. Since the
vertical leg is only 6 mm, the weld does not meet the minimum size requirement. The inspector
must measure the smaller leg to ensure compliance.
Q4 DEMONSTRATE MASTERY OF CORE CONCEPTS
During a visual inspection of a PQR (Procedure Qualification Record) weld, you
notice that the weld deposit has a pronounced columnar grain structure oriented
perpendicular to the weld face. Which welding process is most likely to produce
this characteristic, and what is the primary implication for mechanical properties?
A. SMAW; the grains are fine and isotropic, leading to high toughness in all directions.
B. GMAW; the grains are coarse and directional, leading to anisotropic mechanical properties.
CORRECT
C. FCAW; the grains are equiaxed, leading to uniform properties.
D. SAW; the grains are columnar but have no effect on mechanical properties.
RATIONALE: Gas Metal Arc Welding (GMAW) typically produces a weld with columnar grains
that grow opposite to the heat flow direction, often perpendicular to the weld face. This directional
solidification results in anisotropic mechanical properties, with lower toughness and ductility
across the columnar boundaries. SMAW and FCAW also produce columnar grains but not as
pronounced, and SAW can produce columnar grains but they do affect properties.

, Q5 DEMONSTRATE MASTERY OF CORE CONCEPTS
A visual inspection of a completed weld reveals a surface discontinuity that
appears as a rounded depression at the crater. According to CSA W59, which of
the following is the correct classification and acceptance criterion for this
indication?
A. It is a crater crack and is unacceptable regardless of size.
B. It is a crater and is acceptable if its depth does not exceed 1 mm. CORRECT
C. It is a pipe and is acceptable if its diameter is less than 2 mm.
D. It is a surface pore and is unacceptable if its diameter exceeds 1/8 inch.
RATIONALE: A rounded depression at the crater is characteristic of a crater, not a crack or pipe.
CSA W59 permits craters as long as they do not reduce the effective throat below the required
size, and typically a depth up to 1 mm is acceptable for most welds. Cracks are always
unacceptable, and pores are evaluated by size and frequency, but the description points to a
crater.
Q6 DEMONSTRATE MASTERY OF CORE CONCEPTS
In a visual weld inspection, you measure a fillet weld leg size of 8 mm on both
sides of a T-joint. The weld is made with a 45-degree fillet weld symbol. What is the
theoretical throat thickness, and how does it compare to the effective throat if the
weld has a concave profile?
A. Theoretical throat is 5.6 mm; effective throat is larger because concavity increases the throat.
B. Theoretical throat is 5.6 mm; effective throat is smaller because concavity reduces the throat.
CORRECT
C. Theoretical throat is 8 mm; effective throat is always equal to leg size.
D. Theoretical throat is 4 mm; effective throat is not affected by profile.
RATIONALE: The theoretical throat for a 45-degree fillet weld is 0.707 times the leg size, so
0.707 * 8 = 5.6 mm. In a concave profile, the weld face is depressed, which reduces the
minimum distance from the root to the face, making the effective throat smaller than the
theoretical throat. This can reduce the weld's strength if the throat is below the required size.

C. Minimum size is 6 mm; the weld does not meet the requirement because the horizontal leg is

vertical leg is only 6 mm, the weld does not meet the minimum size requirement. The inspector

theoretical throat thickness, and how does it compare to the effective throat if the

A. Theoretical throat is 5.6 mm; effective throat is larger because concavity increases the throat.
B. Theoretical throat is 5.6 mm; effective throat is smaller because concavity reduces the throat.
CORRECT
C. Theoretical throat is 8 mm; effective throat is always equal to leg size.
D. Theoretical throat is 4 mm; effective throat is not affected by profile.
RATIONALE: The theoretical throat for a 45-degree fillet weld is 0.707 times the leg size, so
0.707 * 8 = 5.6 mm. In a concave profile, the weld face is depressed, which reduces the
minimum distance from the root to the face, making the effective throat smaller than the
theoretical throat. This can reduce the weld's strength if the throat is below the required size.
