Examination Centre: ________________________
Time Allowed: 3 Hours
Total Questions: 120
Instructions: Select the most appropriate answer for each question. All questions are
multiple-choice. Read each question carefully and choose the best answer based on
welding inspection standards, codes, and practices. Calculators are permitted where
necessary.
,Core Competency Areas:
• Welding Processes and Procedures
• Welding Symbols and Drawings
• Inspection Methods (Visual, NDT Basics)
• Metallurgy and Weld Defects
• Codes and Standards Interpretation (CSA W59, AWS D1.1)
• Safety and Quality Assurance
This assessment evaluates the candidate’s competence in welding inspection, fabrication
standards, and applied metallurgy at an intermediate (Level 2) level. Candidates are
expected to interpret welding symbols, assess weld quality, identify discontinuities, and
apply relevant codes and standards in practical scenarios. The exam reflects real-world
inspection challenges requiring both theoretical understanding and applied reasoning.
Instructions to Candidates: Answer all questions. Each question has only one correct
answer. Manage your time effectively to ensure completion. Carefully read all scenarios
before selecting your response. This simulation exam is designed to closely reflect the
structure and difficulty of the official CWB Level 2 certification exam.
,Disclaimer: This is an original simulated examination created for educational and
preparation purposes. It is not an official CWB exam and does not contain actual exam
questions.
Questions
Q1. A welding inspector observes excessive convexity in a fillet weld on a structural beam.
According to CSA W59, what is the most likely concern?
A. Increased ductility
B. Reduced fatigue resistance
C. Improved penetration
D. Lower residual stress
Correct Answer: 🔴 B. Reduced fatigue resistance
Explanation: Excessive convexity creates stress concentration points, reducing fatigue
performance. Option A is incorrect as ductility is not improved. Option C is unrelated, and D
is incorrect since convexity does not reduce residual stress.
, Q2. During inspection, slag inclusions are found in a weld. What is the primary cause?
A. High welding current
B. Improper cleaning between passes
C. Low travel speed
D. Excessive shielding gas
Correct Answer: 🔴 B. Improper cleaning between passes
Explanation: Slag inclusions typically result from failure to remove slag between weld
passes. High current (A) may cause burn-through, not inclusions. Low travel speed (C)
increases heat input, while shielding gas (D) is unrelated.
Q3. A welding symbol shows a triangle below the reference line. What does this indicate?
A. Groove weld
B. Fillet weld on arrow side
C. Back weld
D. Spot weld
Correct Answer: 🔴 B. Fillet weld on arrow side
Explanation: The triangle symbol represents a fillet weld; placement below the reference
line indicates the arrow side. A, C, and D correspond to different symbols.
