Welding Inspector Level 1 Certification Exam
200 Practice Questions with Verified Answers and Rationales
SECTION 1: WELDING FUNDAMENTALS AND PROCESSES (Questions 1-35)
Question 1: What is the primary scope limitation of a CWB Level 1 Welding
Inspector?
A) They may perform ultrasonic testing but cannot interpret results
B) They are restricted to visual inspection only and may not interpret NDT results
C) They may perform magnetic particle testing and interpret findings
D) They are authorized to approve welding procedures and WPS documents
Correct Answer: B
Rationale: CWB Level 1 inspectors are certified for visual inspection only.
Interpreting NDT results requires Level 2 certification. Level 1 inspectors may
witness NDT procedures but cannot interpret or evaluate results .
,Question 2: Under the CWB W178.2 standard, what is the minimum visual acuity
requirement for a Level 1 welding inspector?
A) 20/40 vision, corrected or uncorrected
B) 20/30 vision, corrected or uncorrected
C) 20/20 vision, corrected or uncorrected
D) 20/25 vision, corrected or uncorrected
Correct Answer: C
Rationale: CSA W178.2 requires 20/20 vision (with or without correction), verified
annually. This ensures inspectors can detect fine surface discontinuities .
Question 3: Which welding process uses a non-consumable tungsten electrode?
A) SMAW (Shielded Metal Arc Welding)
B) GMAW (Gas Metal Arc Welding)
C) GTAW (Gas Tungsten Arc Welding)
D) FCAW (Flux Cored Arc Welding)
,Correct Answer: C
Rationale: Gas Tungsten Arc Welding (GTAW) uses a non-consumable tungsten
electrode to produce the weld. The electrode is not consumed during welding,
and filler metal is added separately if needed .
Question 4: What is the primary purpose of a Welding Procedure Specification
(WPS)?
A) To train welders on proper techniques
B) To provide detailed instructions for welding
C) To certify base materials
D) To inspect completed welds
Correct Answer: B
Rationale: A WPS provides the essential variables and instructions required to
consistently produce a sound weld. It defines how a weld must be made to meet
code requirements .
, Question 5: Which type of weld is typically used to join two plates at a right
angle?
A) Butt weld
B) Fillet weld
C) Groove weld
D) Plug weld
Correct Answer: B
Rationale: Fillet welds are commonly used in T-joints, lap joints, and corner joints
where plates meet at right angles. The weld has a triangular cross-section .
Question 6: What does "preheat" in welding help prevent?
A) Porosity only
B) Distortion only
C) Cracking
D) All of the above
