The CWB Welding Inspector Level 1 certification exam consists of four
components: a 75-question closed book fundamentals exam (2 hours, 70%
passing), a 45-question open book code exam (2 hours, 70% passing) based on
documents like CSA W59, a 15-question CSA W178.2 open book exam (0.5
hours, 70% passing), and a practical exam with five weld samples (0.75 hours).
Candidates must first submit application forms including visual acuity verification.
Preparation requires studying the CWB Level 1 textbook, understanding relevant
codes, and practicing with weld gauges. All components must be completed within
two years of application approval.
1. What is the minimum passing grade for the CWB Welding Inspector Level 1
closed book examination?
A) 60%
B) 65%
C) 70%
D) 75%
**Correct Answer: C) 70%**
Rationale: According to CWB certification requirements, all written examination
components for Level 1 require a minimum passing grade of 70%. This ensures
inspectors have a solid understanding of fundamental principles before advancing.
2. Which organization administers the Welding Inspector Level 1 certification in
Canada?
A) American Welding Society (AWS)
B) Canadian Standards Association (CSA)
C) Canadian Welding Bureau (CWB)
D) International Institute of Welding (IIW)
,**Correct Answer: C) Canadian Welding Bureau (CWB)**
Rationale: The Canadian Welding Bureau is the organization responsible for
developing and administering the Welding Inspector Level 1 certification program
in Canada, in accordance with CSA W178.2 standards.
3. During a confined space welding operation, what is the primary responsibility of
the welding inspector before work begins?
A) Ensure breathing air supply line is placed inside
B) Verify the company has a written confined space entry procedure
C) Place a wooden platform inside for worker safety
D) Ensure two safety persons are on hand with a telephone
**Correct Answer: B) Verify the company has a written confined space entry
procedure**
Rationale: Occupational health and safety regulations require a written confined
space entry procedure to be in place before any work commences. This document
outlines hazards, controls, and emergency response plans.
4. When performing receiving inspection on incoming welding consumables, what
is the most critical document to verify?
A) Shipping invoice
B) Material test report (MTR) or certificate of conformance
C) Packing slip
D) Purchase order number
**Correct Answer: B) Material test report (MTR) or certificate of conformance**
Rationale: The MTR or certificate of conformance provides traceability and
verifies that the consumables meet the specified chemical and mechanical property
requirements. Without this, the inspector cannot confirm the material meets
applicable standards.
5. Which welding discontinuity is most likely to be missed by radiographic testing
(RT)?
A) Slag inclusion
B) Porosity
C) Undercutting
D) Tungsten inclusion
**Correct Answer: C) Undercutting**
Rationale: Undercutting is a surface-breaking discontinuity that is oriented along
the weld toe. In radiography, the orientation of undercutting often makes it difficult
to detect because it does not create sufficient density contrast on the film compared
to volumetric defects.
,6. What is the recommended action if a welding inspector discovers that a welder
is not using the required welding procedure specification (WPS)?
A) Immediately stop the welder and notify the supervisor
B) Document the issue after the shift ends
C) Ignore the issue if the weld looks acceptable
D) Ask the welder to continue but work faster
**Correct Answer: A) Immediately stop the welder and notify the supervisor**
Rationale: The welding inspector has the authority and responsibility to stop non-
conforming work immediately. Allowing work to continue outside the approved
WPS compromises weld quality and safety. Documentation and notification follow
the stop-work action.
7. Which type of visual inspection aid is most appropriate for measuring the root
opening of a joint prior to welding?
A) Fillet weld gauge
B) Bridge cam gauge
C) Steel rule or taper gauge
D) Magnifying glass
**Correct Answer: C) Steel rule or taper gauge**
Rationale: Root opening is a linear measurement between two joint members. A
steel rule or taper gauge can accurately measure this gap. Fillet weld gauges are
designed for finished fillet weld dimensions, not pre-weld joint fit-up.
8. According to CSA W59, what is the maximum allowable reinforcement for a
butt weld in bridge construction?
A) 1 mm (0.04 in)
B) 3 mm (1/8 in)
C) 5 mm (3/16 in)
D) No limit specified
**Correct Answer: B) 3 mm (1/8 in)**
Rationale: CSA W59 specifies maximum reinforcement of 3 mm for butt welds in
most applications, including bridges. Excessive reinforcement can create stress
concentration points and may interfere with subsequent operations.
9. What does the acronym "HAZ" stand for in welding metallurgy?
A) High amplitude zone
B) Heat affected zone
C) Hardened alloy zone
D) Hydrogen absorption zone
, **Correct Answer: B) Heat affected zone**
Rationale: The heat affected zone is the area of base metal adjacent to the weld that
has undergone microstructural changes due to the heat of welding but has not been
melted. This zone is critical for inspection because it can contain hardness
variations and potential cracking.
10. Which cleaning method is NOT recommended prior to liquid penetrant testing
(PT)?
A) Cleaning with organic solvents
B) Blasting with shot or dull sand
C) Cleaning with degreasers
D) Ultrasonic cleaning
**Correct Answer: B) Blasting with shot or dull sand**
Rationale: Shot or sand blasting can peen over the surface and close
discontinuities, preventing penetrant from entering defects. This leads to false
negative results. Chemical cleaning or gentle methods that do not deform the
surface are preferred.
11. What is the primary purpose of a welding procedure specification (WPS)?
A) To provide a resume of the welder's qualifications
B) To list the company's safety policies
C) To provide detailed instructions for producing a sound weld
D) To document the cost of welding consumables
**Correct Answer: C) To provide detailed instructions for producing a sound
weld**
Rationale: A WPS is a written document that provides direction to the welder on
essential variables such as amperage, voltage, travel speed, preheat, and interpass
temperature to ensure repeatable, quality welds.
12. When performing a visual inspection of a fillet weld, the inspector observes a
convex face. What is the typical maximum allowable convexity per CWB
standards?
A) 1 mm (0.04 in)
B) 2 mm (5/64 in)
C) 3 mm (1/8 in)
D) 5 mm (3/16 in)
**Correct Answer: C) 3 mm (1/8 in)**
Rationale: Most codes, including CSA W59, limit fillet weld convexity to 3 mm
unless otherwise specified. Excessive convexity can create stress risers and does
not contribute to weld strength, only adding unnecessary weld metal.
