CSA W59 & W47.1 STANDARDS | GRADED A
1.
A Level 3 welding inspector is assigned to review a structural steel fabrication
project in which several welds appear visually acceptable, but production records
show that the welders used parameters outside the limits established by the
approved welding procedure. What should be the inspector's primary concern?
A. The weld appearance is acceptable, so no further action is required
B. Compliance with the approved welding procedure and applicable requirements
must be verified
C. Only radiographic examination can determine whether the welds are acceptable
D. The welder may select any parameters if the final weld passes visual inspection
Answer: B
2.
A welding inspector reviewing fabrication documentation discovers that a
company is certified for fusion welding of steel but has transferred responsibility
for final weld quality entirely to an outside inspection agency. Which principle is
most important?
A. The inspection agency assumes all responsibility for weld quality
B. The certified company retains responsibility for the quality of its welded
product
C. Responsibility automatically transfers to the welding engineer
D. Responsibility belongs exclusively to the purchaser
Answer: B
3.
During inspection of a multi-pass groove weld, an inspector observes elongated
dark lines between deposited weld passes. The discontinuities follow the interface
between successive weld beads. Which condition is most likely?
,2
A. Incomplete fusion
B. Lamellar tearing
C. Hot cracking
D. Crater cracking
Answer: A
4.
Before welding begins, an inspector notices that joint preparation dimensions differ
significantly from those shown on the approved drawing and welding procedure.
What should be done first?
A. Allow welding and inspect the completed weld
B. Document the condition and ensure the discrepancy is resolved before welding
C. Increase the welding current
D. Allow the welder to compensate by depositing additional weld metal
Answer: B
5.
A welding inspector must determine whether a welding procedure may be used for
a particular production application. Which document normally provides the
detailed instructions required by the welder during production?
A. Inspection report
B. Welding Procedure Specification
C. Welder identification card
D. Material test certificate
Answer: B
6.
Which inspection activity is generally performed before welding begins?
A. Verification of final weld reinforcement
B. Measurement of undercut
C. Confirmation of joint preparation and material identification
D. Examination for surface porosity after cleaning
,3
Answer: C
7.
During visual inspection, a crack is discovered in the weld metal. Regardless of its
apparent size, what should generally be the inspector's primary response?
A. Ignore it if reinforcement is adequate
B. Evaluate it according to applicable acceptance requirements and initiate
appropriate corrective action
C. Grind the crack without documentation
D. Increase the weld size and leave the crack in place
Answer: B
8.
A fabrication company wishes to maintain certification for fusion welding of steel.
Which combination represents major elements associated with certification
requirements?
A. Personnel, welding procedures, and appropriate equipment
B. Paint certification and architectural approval only
C. Radiographic testing only
D. Purchasing inspection instruments only
Answer: A
9.
An inspector finds that a welder performing production work is not currently
qualified for the applicable welding process and conditions. What is the most
appropriate action?
A. Allow completion if the welder has previous experience
B. Permit welding only if another qualified welder observes
C. Stop or prevent unauthorized welding and verify qualification requirements
D. Accept the work if visual examination is satisfactory
Answer: C
, 4
10.
Why is preheat monitored during structural welding?
A. To increase the color of the weld bead
B. To control thermal conditions that can affect weld quality and hydrogen-related
cracking risk
C. To eliminate the need for procedure qualification
D. To increase travel speed regardless of material thickness
Answer: B
11.
An inspector measures excessive root opening compared with the specified joint
preparation. What potential welding problem is most directly associated with this
condition?
A. Difficulty controlling penetration and weld profile
B. Elimination of distortion
C. Guaranteed reduction in weld metal volume
D. Automatic prevention of incomplete penetration
Answer: A
12.
Which of the following is the best description of a welding discontinuity?
A. Any condition that differs from the ideal weld profile
B. A condition that always requires rejection
C. An interruption or irregularity in the intended weld structure or geometry
D. A defect that has already been rejected
Answer: C
13.
A discontinuity becomes a rejectable defect when:
A. It is visible to the unaided eye
B. It exceeds applicable acceptance criteria
