INTRODUCTION
This comprehensive CWB Welding Inspector Level 2 Exam Prep Study Guide
contains practice questions with verified answers and detailed explanations,
specifically designed for the Canadian Welding Bureau Level 2 Welding Inspector
Certification Examination for 2026/2027. The guide covers every major topic
tested on the exam including engineering drawings (isometric with 30° angles,
orthographic with 6 maximum views, perspective vs isometric), welding joints and
symbols (5 basic joints, 5 basic weld types, weld symbol vs welding symbol, size
placement), plasma arc cutting (30,000°C temperatures, DCEN polarity,
transferred/non-transferred arc), and all key concepts from every module. Based
on actual exam screenshots and expected content, this complete resource
provides welding professionals with everything needed to achieve a Grade A score
on the CWB Level 2 certification examination.
SECTION 1: ENGINEERING DRAWINGS - ISOMETRIC & ORTHOGRAPHIC
Question 1
In an isometric drawing, the lines (for width, length, and depth) are inclined at an
angle of how many degrees?
,A) 15°
B) 30°
C) 45°
D) 60°
E) 90°
VERIFIED ANSWER: B) 30°
EXPLANATION: In an isometric drawing, the lines for width, length, and depth are
inclined at an angle of 30° to the horizontal. This creates the three-dimensional
appearance of the object. The isometric projection is a type of axonometric
projection where the three axes appear equally foreshortened and the angles
between them are 120°. The 30° angle is standard for isometric drawings in North
America. This is one of the two general classes of picture drawings (the other
being perspective).
Question 2
What are the maximum number of views in an orthographic drawing?
A) 2
B) 3
C) 4
D) 6
E) 8
VERIFIED ANSWER: D) 6
EXPLANATION: The maximum number of views in an orthographic drawing is 6.
These are the six principal views: TOP, FRONT, RIGHT SIDE, LEFT SIDE, BOTTOM, and
REAR. However, in North America, the three orthographic views most commonly
,used are TOP, FRONT, and LEFT SIDE. Orthographic projection uses parallel lines of
sight perpendicular to the projection plane to create two-dimensional
representations of three-dimensional objects.
Question 3
In North America, the three orthographic views most commonly used are TOP,
FRONT, and which side?
A) RIGHT Side
B) LEFT Side
C) BOTTOM
D) REAR
E) All of the above
VERIFIED ANSWER: B) LEFT Side
EXPLANATION: In North America, the three orthographic views most commonly
used are TOP, FRONT, and LEFT SIDE. The LEFT SIDE view is the standard third-
angle projection used in North American drawing standards (ANSI). In Europe,
first-angle projection is used, which shows the RIGHT side view. Understanding the
projection system is essential for reading engineering drawings.
Question 4
What are the two general classes of picture drawings?
A) Isometric and Orthographic
B) Perspective and Isometric
C) Orthographic and Perspective
, D) 2D and 3D
E) Plan and Elevation
VERIFIED ANSWER: B) Perspective and Isometric
EXPLANATION: The two general classes of picture drawings are Perspective and
Isometric. Perspective drawings show objects as they appear to the eye, with
parallel lines converging to vanishing points. Isometric drawings show objects in
three dimensions with lines inclined at 30° to the horizontal. Both are used to
create pictorial representations of objects for engineering and design purposes.
Question 5
In a perspective drawing, parallel lines converge to:
A) The center of the page
B) Vanishing points
C) The top of the page
D) The bottom of the page
E) The horizon line
VERIFIED ANSWER: B) Vanishing points
EXPLANATION: In a perspective drawing, parallel lines converge to vanishing
points. This creates a realistic representation of how objects appear to the human
eye. Vanishing points are points on the horizon line where parallel lines appear to
meet. Perspective drawings can have one, two, or three vanishing points
depending on the complexity of the drawing.
Question 6
What is the difference between a first-angle and third-angle projection?
