CWB WELDING INSPECTOR LEVEL (1-3)
EXAM 2026/2027 | WELDING INSPECTION |
100 VERIFIED Q&A | DETAILED RATIONALES
| PASS GUARANTEED – A+ GRADED
SECTION 1: WELDING PROCESSES & EQUIPMENT – Questions 1-20
Q1: Welder Test Position – 2G
Which of the following refers to a welder test where a pipe assembly is placed vertically and the
joint welded in the horizontal position without rotating the assembly?
A. 1G
B. 2G
C. 3G
D. 5G
Correct Answer: B
Rationale: The 2G position involves a pipe placed vertically with the joint welded in the
horizontal position without rotating the assembly. This is a standard welder qualification test
position.
Q2: SMAW Electrode Restricted to Flat and Horizontal
Which one of the following SMAW electrodes is restricted to horizontal and flat position welding?
A. EXX18
B. E4916
C. EXX10
D. E4924
Correct Answer: D
Rationale: E4924 electrodes are restricted to horizontal and flat position welding due to their
heavy iron powder coating, which produces a large molten weld pool that is difficult to control in
vertical or overhead positions.
Q3: AC Welding Circuit Advantage
,An advantage of an AC welding circuit is:
A. It requires less equipment
B. It eliminates arc blow
C. It provides deeper penetration
D. It is more efficient
Correct Answer: B
Rationale: AC welding circuits help eliminate arc blow (magnetic arc deflection), which is a
common problem with DC welding.
Q4: Cutting Process – Narrowest HAZ
Select the cutting process that would provide the narrowest heat affected zone when cutting
12.5 mm (0.5 in) thick carbon steel.
A. Oxy-fuel cutting
B. Plasma arc cutting
C. Laser beam cutting
D. Air carbon arc cutting
Correct Answer: C
Rationale: Laser beam cutting produces the narrowest heat affected zone due to its highly
focused energy beam, which minimizes heat input to the surrounding base metal.
Q5: GMAW Short-Circuiting Transfer in Overhead
When performing GMAW in the overhead position using the short-circuiting arc metal transfer
method, which of the following is NOT an advantage?
A. Small molten weld pool size
B. Improved bead contour
C. Efficient metal transfer
D. Speed, high rates of travel are possible
Correct Answer: A
Rationale: Short-circuiting transfer in the overhead position does not produce a small molten
weld pool. The other options are advantages of the process in this position.
Q6: Slag Function in Welding
,The main function of slag is to:
A. Protect the weld metal from contamination and control bead shape
B. Increase welding speed
C. Reduce heat input
D. Improve penetration
Correct Answer: A
Rationale: Slag protects the weld metal from atmospheric contamination during cooling and
helps control the bead shape and smoothness.
Q7: FCAW Electrode Classification
The major category of gas shielded tubular electrodes is:
A. Rutile types
B. Basic types
C. Cellulosic types
D. Acid types
Correct Answer: A
Rationale: Rutile types are the major category of gas shielded tubular electrodes (FCAW). They
provide good arc stability and smooth bead appearance.
Q8: GMAW Transfer Mode – Short-Circuiting
Which GMAW metal transfer mode is characterized by low heat input and is suitable for thin
materials?
A. Spray transfer
B. Globular transfer
C. Short-circuiting transfer
D. Pulsed spray transfer
Correct Answer: C
Rationale: Short-circuiting transfer (short-arc) produces low heat input and is suitable for thin
materials and out-of-position welding.
Q9: SAW Flux Function
What is the primary function of flux in Submerged Arc Welding (SAW)?
, A. Protect the arc and weld pool from atmospheric contamination
B. Increase welding speed
C. Reduce heat input
D. Improve penetration
Correct Answer: A
Rationale: In SAW, the granular flux blanket protects the arc and molten weld pool from
atmospheric contamination.
Q10: FCAW Shielding Gas
What type of shielding gas is commonly used with FCAW?
A. 100% argon
B. 100% helium
C. CO₂ or CO₂/argon mixtures
D. 100% nitrogen
Correct Answer: C
Rationale: FCAW commonly uses CO₂ or CO₂/argon mixtures as shielding gases, providing
good penetration and arc stability.
Q11: Welding Position – 6G
What does the 6G welding position refer to?
A. Pipe inclined at 45 degrees
B. Pipe in the horizontal position
C. Pipe at 45 degrees with no rotation
D. Pipe in the vertical position
Correct Answer: A
Rationale: The 6G position involves a pipe inclined at 45 degrees with the joint welded without
rotation. This is the most difficult pipe welding position.
Q12: Oxy-Fuel Gas Cutting
What is the primary function of the cutting oxygen stream in oxy-fuel gas cutting?
A. To heat the metal
