CSA W59 WELDING INSPECTOR LEVEL 1 EXAM
QUESTIONS AND ACTUAL COMPLETE
ANSWERS 2026 UPDATED.
Overview:
This exam is designed to prepare candidates for the CSA W59 Welding Inspector Level 1
Certification, focusing on the visual inspection of steel welds and understanding CSA W59
standards.
It covers:
Welding Processes & Terminology: SMAW, GMAW, GTAW, flux-cored welding, and
fusion principles.
Inspection Techniques: Visual inspection, weld gauges, mirrors, lighting, and proper
measurement methods.
Weld Discontinuities: Cracks, porosity, undercut, overlap, lack of fusion, incomplete
penetration, and crater cracks.
Weld Symbols & Drawings: Interpretation of CSA W59 welding symbols including fillet,
groove, field, and all-around welds.
Acceptance Criteria: Major vs. minor discontinuities, dimensional tolerances, and
criteria per CSA W59.
Documentation & Safety: Proper inspection records, personal protective equipment, and
site safety requirements.
1.
Which of the following best describes fusion welding as defined in CSA W59?
A. Joining without melting the base metal
B. Joining metals by coalescence through heating
C. Adhesive bonding
D. Mechanical fastening
,**Correct Answer: **B
Rationale: Fusion welding involves melting the base metal to form a joint; CSA W59
governs fusion welding of steel structures.
2.
In visual inspection, a weld surface should be evaluated for:
A. Color only
B. Surface discontinuities such as cracks, undercut, overlap
C. Internal porosity invisible to the eye
D. Base metal strength
**Correct Answer: **B
Rationale: Visual inspection focuses on observable surface irregularities and
discontinuities.
3.
A common surface discontinuity that results from inadequate heat input is:
A. Underfill
B. Porosity
C. Crater crack
D. Excessive convexity
**Correct Answer: **C
Rationale: Crater cracks often occur due to abrupt termination of welding heat.
4.
What does the term weld reinforcement refer to?
A. Extra filler metal above the weld face
B. Internal reinforcement only
,C. Base metal thickness
D. Groove depth
**Correct Answer: **A
Rationale: Weld reinforcement is the additional weld metal above the base material
surface.
5.
Which of the following is a major discontinuity under CSA W59 criteria?
A. Minor undercut within tolerance
B. Cracking
C. Slight overlap within limits
D. Small surface porosity
**Correct Answer: **B
Rationale: Cracking is considered a major discontinuity that affects structural integrity.
6.
CSA W59 classifies weld acceptance criteria based on:
A. Weld length only
B. Joint type, thickness, and end use
C. Cost of material
D. Welder preference
**Correct Answer: **B
Rationale: Acceptance criteria consider joint design, thickness, and service conditions.
7.
A Level 1 Welding Inspector should be competent in:
, A. Performing nondestructive testing only
B. Basic visual inspection and understanding W59 criteria
C. Designing weld joints
D. Welding certification
**Correct Answer: **B
Rationale: Level 1 focuses on visual inspection and basic interpretation of criteria.
8.
Which tool is essential for measuring weld size?
A. Mechanical caliper or fillet weld gauge
B. Hammer
C. Tape measure only
D. Protractor
**Correct Answer: **A
Rationale: Calipers and weld gauges accurately measure weld dimensions.
9.
A weld profile shows excessive convexity beyond limit. What is the inspector’s immediate
action?
A. Accept if strength is adequate
B. Evaluate against acceptance criteria and document if noncompliant
C. Ignore minor issues
D. Repair without documentation
**Correct Answer: **B
Rationale: Excessive convexity must be documented and evaluated against CSA W59
limits.
